Increase your environmental friendly drilling efficiency with GN Solids Control products, one of the most important equipment is the Solidification / Stabilisation unit. The drill cuttings solidification unit is advanced and unique, which is quite flexible comparing the waste cuttings solidification plants.

Solidi cation – Is an absorption process where contaminants, typically oils, are taken into the absorbent material in the same way a sponge takes on water. In general, solidi cation is the addition of absorbents such as soil, y ash, kiln dust, cement, clays or sawdust to the drilling waste management . The solidi ed product will have improved properties such as strength, compressibility and a reduced permeability.

Stabilisation – Is an adsorption process whereby contaminents are electrochemically bonded to the stabilising agents. Contaminants that are stabilised within the matrix are less likely to be released into the environment. This process is particularly relevant to the stabilisation of heavy metals and oils that would otherwise be rapidly available to the environment through leaching.

The adeptness to coalesce or stabilise a accurate decay beck and the e ectiveness of the analysis is abased on the decay blazon and analysis reagent factors. Typically, adumbrative samples of the decay are class activated to actuate the a lot of acceptable conception above-mentioned to eld implementation. Selection of the conception is commonly based on key belief such as leachate superior and backbone of the nal product.

Decanter centrifuge for HDD

Decanter centrifuge is seldom used for plan directional drilling because of the high-cost and separation factor. Only if the fine solids gathered on the mud recycling system and the desilter cone cannot separate them out, then this recycled mud can not be employed for drilling unless the great solids (smaller than 12-15 microns) could be reduced. GN low speed/ middle acceleration decanter centrifuge GNLW452 centrifuge should be used by such circumstance.

“Decanter centrifuge for Horizontal Directional Drilling”的图片搜索结果

GN has shipped several sets of 1000gpm mud recycling system with a couple of units of GNLW452 decanter centrifuges for CPP(China Oil Pipeline Bureau) for their traversing project. Totally 4 value packs of desander mud clean with 2 10inch desander cone and double veranda shale shaker GNZS705, 5 sets of desilter magnetic cleaner with 10pcs 4inch desilter cones with two times deck shale shaker, eight sets of GNLW452 decanter centrifuge with 18inch serving diameter, 1800rpm speed, 7 sets of centrifugal pushes to feed for the desander, desilter, 8 sets regarding feeding pump for the decanter centrifuges. 8 sets connected with 20ft container to install typically the equipments on it and with memory space.
This is not the first order through CPP, they start to purchase mud recycling system regarding HDD since 2010, and also until now they already purchased 30 sets of going mud cleaning system through GN solids control.
Typically the function of the decanter centrifuge in this system is not to different all the fine solids within 15 microns, the purpose should be to reduce the fine solids information in the recycled fluids therefore it can be re-used for the going. So the centrifuge capacity aren't required to equal with the solids control mud cleaner, it is not generally running, we will open it depending on the mud conditions.
Not only to get HDD mud recycling program, the same design could be utilized for tailings treatment of mining, essential oil drilling. Welcome to contact GN solids control for more info.

Choose GN’s Pump for Different Application

The drilling mud could be seen as the blood of the drilling process, the solids control equipment is used to remove the cuttings to purify the blood. While where is the power of the blood circulation coming from? It is the pump unit that transfers the drilling mud in solids control system from one equipment to another, make the continuously recycling of mud available.

As a leading China based solids control equipment manufacturer, GN solids control could provide the full line of equipment used for drilling mud cleaning. Besides the primary solids control equipment like shale shaker, mud cleaner and centrifuge unit, GN also provides several types of pump for different application in mud recycling system.

Centrifugal pump is the most widely used mud transferring equipment. This type pump uses tungsten carbide mechanical seal, with open design of impeller that lowers the axial thrust load. Centrifugal pump could be used as feeding pump for de-sander and de-silter cyclone unit. For some deep drilling project, the mud system need a trip tank, this type pump can also be used as trip pump. The jet mud mixer unit always equipped with centrifugal pump as mud mixing pump to transfer chemicals into the drilling mud.

Shearing pump is also always equipped with mud hopper. With the impeller material of high wear resistant cast iron, the shearing pump is used to shear the polymers that used in the drilling mud to keep proper mud specific gravity. GN’s shearing pump is available as a belt-driven or diesel-driven package including hopper, mud gun and transfer line orifice plate.

GN’s PD pump is a single screw pump. This pump is an ideal chosen for feeding to decanter centrifuge unit as it transfer the drilling mud without shearing and agitating. This pump, with stator material of elastomeric material, has particular advantages to transfer fluids of high viscosity and hard suspended particles included.

Vertical submersible slurry pump is another choice as feeding pump to centrifuge. This pump is always installed vertically to transfer medium with high concentration particles. Submersible pump is also widely used to transfer the mud from mud pit to the shale shaker in the HDD mud recycling system.

Dewatering System for Water Hammer

Not only drilling, whenever there is a construction work, or some work, there must be some waste generated, planning before proceed have been more and more important. Some clients who is using water hammer, also is going to do with the waste, and reuse the water.

As we all know there are 4 basic rules of waste handling to make it envronmental friendly. Reduce, reuse, recycle, recover. For water hammer, one of the most important reason is we need to recyle and reuse the clean water.

Reuse – solids control equipment is key to the reuse strategy. Poor solids control efficiencies will lead to more solids entering the active system, further reducing their particle size, and ultimately resulting in the requirement to dump, or to dilute, thereby increasing volumes and costs, all of which have a negative environmental impact.

The water hammer which is normally more expensive than the normal drilling rig, especially for the use of the water, not drinking water but need to be as clean as possible.

2015.11.16 GN mud system with shaker and centrifuge

Therefor now we are deliverying one system to Europe, which is used for water hammer project. Containing:

1) Double deck shale shaker: GN double deck shale shaker can remove the solids in very good performance, top section screen with sieve screens remove most of the big particles.

2) Decanter centrifuge: GN decanter centrifuge is used to remove the fine solids, min separation points about 2-5microns. Sometimes it need to be used with polymer, the dewatering unit, to make sure we get the better result.

3) Screw pump: screw pump feed for centrifuge. The pump from GN is made by German Netsch, NEMO pump makes sure the performance of centrifuge feeding.

4) Mud tank skid: All equipment is mounted on one mud tank, which is also able to be customized. Normally minimum requirement is to lower the transportation cost.

What is "IECEX/A-TEX" mark on GN Solids America’s solids control machines?

Oil rig drilling is world-wide operation and solids control machinery and system is manufacture t that it can be operate on any corner of the world, land and sea alike. As been one of the most hazard working- area condition, the electronic parts of machinery often marked "IECEX/A-TEX". This is the certificate marked as Hazardous Area Certifications. The mainstream mark is IECEX which is international which every country accept the standard while ATEX is European standard but most countries are accept the standard as well.

Explosive atmospheres can be caused by possible burning gases, mists, vapors or by combustible dusts, in combination with oxygen. With a certain concentration density all that is needed to cause an explosion is a source of fire cause by heat and spark.

ATEX or IECEX certified machinery will secure the operators and its machinery assets that under no matter in any working condition it will not cause an ignition so in conclusion it is safe, end of discussion. The standard divided into different zones that ID potential hazardous atmosphere in the area.

ATEX based on the requirements of two European Directives:

1. Directive 99/92/EC (also known as ‘ATEX 137’ or the ‘ATEX Workplace Directive’) is minimum requirements for improving the health and safety protection of workers potentially at risk from explosive atmospheres.

2. Directive 94/9/EC (also known as ‘ATEX 95’ or ‘the ATEX Equipment Directive’) on the approximation of the laws of Members States concerning equipment and protective systems intended for use in potentially explosive atmospheres.

What IECEX Scheme is an international Conformity Assessment Scheme covering Electrical Equipment for Explosive Atmospheres, as the internationally accepted means of demonstrating conformity with IEC Standards prepared by IEC TC31.

ATEX standard is about enabling to trade in European countries. Its purpose is to establish a level of safety which is to be regarded it is sufficient to ensure European authorities would accept the equipment certified.

Difference compare with ATEX, the IECEX is about giving confidence that a product or service meets clearly defined transparent criteria. By providing its transparency with a high level of confidence, it is intended that it will eventually provide a worldwide recognized and acceptance certificate in which the whole world has confidence. The driving force is safety, with the trade benefits following from the confidence.

Principle And Theory Of Centrifuge Operation

The centrifuge workds with an principle of accelerated settling , centrifuge G force will help solisd settling much quicker . Let’s think about a simple sedimentation vessel to understand it’s working principle , the solids in fluids will settle to bottom of the sedimentation vessel by a period of time later . In a drilling fluids that weight 14 lb/gal and 50 micron barite particle will settle at the same rate as an 81 micron drill solids . All solids can have a detrimental effect on the drilling fluids viscosity . That means a low specific gravity solids will has an equivalent spherical diameter that is 1.6 times that of a barite solids and settle at the same rate as the barite particle . This is the reason that a centrifuge does not separate varite from low gravity solids .
Modular Drilling Waste Management

The convey of solids out of the decanter centrifuge , the conveyor and bowl mus rotate at slightly different speed . This is accomplished using a planetary gear box for belt drive centrifuge and typically the entire assembly rotates in the same direction but the conveyor rotates at a slightly slower speed . The conveyor will move drilling solids to the solids discharge end and the fluids part out of the liquid discharge end .

The centrifuge will provide a method of increasing the settling force on the drilling solids suspended in fluids . The force depends on the mass of the solids and not the chemical composition . Drilling solids with the same mass , maybe barite or low gravity solids or gold or something , it will settle at the same rate . The decanter centrifuge are able to separatesolisd above and bellow the 2 to 10 micron size range . In the weighted drilling mud , the centrifuge will be capable of eliminating very small particals because of dramatic increase in both low and high shear rate viscosity .

GN Solids America is the first USA based China solids control company. GN’s products are equal in quality and performance as its US and European peers. It is sure to better serve the end users.

GN can offers customized solutions on the drilling waste management field Welcome you contact GN group freely for solution.

Shale shaker purpose

The shale shakers are mainly powered by the rotation motors to rotate and produce the periodic changed passivity force, drilling fluid that contain solid phase pass through the mesh screen, do the forcing movement on the mesh surface, and then the solid phase debris with various size will be filtered. The separation sizes and through put of the shale shakers is the most important factors of making use decision. The technology level of shale shakers mainly show at the treating capacity, the stability of filter debris, the life of operation and the flexibility of operation. The managing ability of shale shakers is related with the structure of shale shaker steel body, the movement arrangement, the vibration frequency, the vibration intensity, the working area of shale shakers and the degree of thickness. In order to make the shale shakers match with the drilling machineries, the maximum outputs of the drilling pumps and the quantity of drilling cuttings filtered must be considered.

Shale shaker is one of the main products of GN solids control .GN sell a series of solids control equipment and drilling waste management equipment including vertical cuttings dryer , shale shaker , screw conveyor , shear pump , oilfield shale shaker , mud cleaner , desander and desilter , vacuum degasser , poor boy degasser , decanter centrifuge , mud tank , mud agitator , etc .

The classification of shale shaker

It depends on the movement arrangement; the shale shakers can be grouped into round screen shaker, the common elliptic screen shaker, linear screen shaker, equilibrium elliptic screen shaker. The common elliptic screen shaker: also can be called the disequilibrium elliptic screen shaker, there is a exciter devices fixed right above of the screen box , the screen boxes may tilt an angle, use the leverage of the gravity, avoids the sand having the tendency of back flowing. From this, the tilt of the screen boxes really improved the flowing performance of sand, but the disposed amount of the drilling fluid reduced, this is the main disadvantage of the common elliptic screen shaker. The linear shale shakers: Two main axises with eccentric blocks do synchronous reverse rotation to produce the liner vibration. Because the direction of the liner shale shaker is unchanged, which makes the debris difficult to fall through, and then the screen paste aspect appears, which makes the valid over flowing area of screen and throughput reduced. When the number of screens increases, the aspect of screen paste will be more serious. So when the linear shale shakers use the super fines screen, it could not meet the requirements of the using amount of drilling fluid.

GN Series Pumps Used for Solids Control and Waste Management

Besides the main equipments used for solids control and waste management systems and HDD, CBM, Piling drilling projects, like the shale shaker, desander, desilter, mud cleaner, decanter centrifuge and vertical cuttings dryer, GN also produce suitable and reliable auxiliary equipments including mud agitator, mud gun, jet mud mixer and various of pumps.

Below are some popular pumps and their applications for your information:

1. centrifugal pump GNSB Series, which is also called sand pump. It uses centrifugal force to suck the material and feed to the main equipments. In a complete system, it is widely used like the desander cones feeding pump, desilter cones feeding pump and also the mixing pump for the jet mud mixer. In trip tank for a large solids control system, centrifugal pump is also used.

In a mud recycling system for the HDD, CBM, TBM or Piling, in most cases, centrifugal pumps are used as desander or desilter cones feeding pump also, and also mixing pump for the jet mud mixers. Sometimes, per client special request, it could be replaced by a horizontal slurry pump when serving as desander or desilter feeing pump.

2. shearing pump, plays similar role as centrifugal pump, but in some special chemical transportations, it is feeding pump for jet mud mixer also and because of the different design, it could also cut the chemicals during transportation.

3. submersible slurry pump, it serves mainly 2 applications in GN series solids control system and waste management systems, the first one is centrifuge feeding pump for GNLW363 decanter centrifuges, GNLW452 decanter centrifuges and etc. The second one is the feeding pump for a mud recycling system for HDD, CBM, TBM and piling works. Unless the oil and gas drilling rig jobsite, where the drilling mud could flow directly to the shale shaker, in such mentioned projects, the mud for treating mostly comes from the mud pit. A submersible slurry pump can help to suck mud from the mud pit to the system.

4. screw pump or called mono pump. GN is not manufacturing this screw pump, but in order to match suitable screw pump for the centrifuges, GN cooperate with the German brand Netsch. Screw pumps are most suitable solution for feeding the decanter centrifuges.

May you need any of them, welcome to contact us freely.

Why The Drilling Waste Should Be Treated or Handled

Where is a well being drilled, where is the waste generated. The wastes generated by drilling vary from the drilling fluids used for drilling and the drilling site, but generally include drilling cuttings, waste water, spent drilling fluids, completion fluids and filtration wastes. Absolutely the wastes are contaminants to the surrounding ground and water if directly buried in the mud pit. With increasing public awareness of the damage caused by the wastes, the stricter environmental standards and regulations on drilling activities, the significance of the handling and treatment of has attracted the eyes of drilling contractors and increased in different degrees around the world.

The handling and treatment process depends largely on the local regulation of a country, while in a country where there is no environmental regulation on the drilling activities, the drilling contractor will fall back on minimum standards used in other countries or standards set at a corporate level. Generally, 4Rs can be used to describe the process of handling and treatment of the drilling wastes: Reduce&Reuse&Recycle&Recover. Reduce means reducing the wastes by some methods such as precise plan, smaller bole and selection of drilling fluids. It would be perfect if no waste generated when a well is drilled. Reuse means cleaning the waste to collect active drilling fluids by solids control equipment normally including shale shaker as 1^st phase, desander& desilter or mud cleaner as 2^nd and 3^rd phases, and decanter centrifuge as the final phase. Recycle means to further treat the drilling cuttings after Recycle after the recovery of the drilling fluid for reuse. Recover means to make the drilling cuttings into a hydrocarbon by high temperature treatment. Though the recovered hydrocarbon can not be used as drilling fluids, it can be used for a fuel material.

GN Solids Control Mud Recycling System for No Dig Projects

Starting from solids control equipment and system for oil and gas drilling, Hebei GN Solids Control Co., Ltd has developed a complete line of product related to solids control in various activities not only limited to the oil and gas drilling, such as horizontal directional drilling, abbreviated as HDD, tunneling, geothermal drilling, water well drilling and so on. As the top manufacturer in China, Hebei GN Solids Control Co., Ltd has been leading the way in solids control for no dig projects with a international brand GN Solids Control achieved. Until now, GN Solids Control has over 20 sets mud recycling system work in Australia for HDD or CBM project. What’s more, GN will attend 2015 AustraliaNo Dig Show around 1 month later, bringing its standard design of mud recycling system with the capacity of 200GPM to this show.

GN mud recycling system is composed with drill solids separation machines and mud mixing device, model being divided by the treating capacity into G200, G350, G500, G1000. For small treating capacity models, GN uses a double deck mini cleaner with the combination of shale shaker and desilter cones on the top. The bottom deck serves as the first phase treating machine to remove coarse solids thus reducing the solid loading on the desilter cyclones and increasing the treating efficiency of desilter cyclones. The desilter cyclones will separate finer solids out to make the mud clean enough to return the active system after mixed. The treating capacity depends on the quantity of the desilter cyclones. For large treating capacity models, GN uses a shaleshaker as thefirst phase treating machine, and a desander or a desilter as the second phase treating machine, then a desilter as the three phase treating machine if needed.

Another Drilling Waste Management System to Russia

The market is pretty quite, but China drilling waste management market is booming. From a few years ago, when we decided to invest on the driling waste managment, we never estimated the demand will be far more than solids control system.

Beyond that, GN is the first company exported drilling waste management system to Russia, and at the first time, it is to big players, Baker Hughes. Now more and more Russian clients knows us, and get in touch with us. One more system to Russia recently.

After sent the unit to Baker Hughes, and get very good feedback, it becomes a very popular design, also more and more competitors do the similar modifications.

Basicly, it contains a cuttings dryer, and a centrifuge, c/w feeding pumps, flushing pumps, feeding screws, intermediate tanks, and flexible lifting frame supportings.

For more convenient layout on site, we also have separate modular parts options. This will be shown in Shanghai CIPPE exhibition.

Modular units for drilling waste management is becoming more and more popular, because of the small dimension and small weight, flexible for transportation and jobsite layout. Different kinds of soft pipes, screw conveyors and pumps are the blood vessel of the whole drilling waste management system, to connect the key equipment. GN SolidsControl will take the key equipment to oil show.

For the all in one system, it is more convenient to move the whole system. And after settled, the postion of the equipment is certain, for long time operations, this is easier for all theon siteoperaters.

Remark: GN vertical cuttings dryer can also be used for WBM drilling cuttings treatment. Compared with High G dryer, the treatment results is much better, however, the power consumption is much bigger. The vertical cuttings dryer is 55kw for big size cuttings dryer (GNCD930 dryer) and 37kw for mini vertical cuttings dryer (GNCD730 dryer); only 3.88kw for High G dryer (GNZS594HGE-LD). Operation cost of vertical cuttings dryer and high G dryer is almost same. The most costly operation parts for vertical cuttings dryer is screen basket; the most costly operation spare parts for high G dryer is shaker screen. They both need to be replaced after some period use.

Also a lot of customized choices are availalbe, kindly let us know your requirement, then we can supply you with the right solutions.

The ways Solidification/Stabilization works

The treatment of solidification/stabilization "s/s" is the treatment of environmentally-harmful; wastes for disposal, reuse and/or site storage of land on contaminated. It is the S/S treatment involves harmful materials mixing a binding reagent into the contaminated materials or waste. Although the terms solidification and stabilization sounds close-meaning by hearing, they describe different effects that the binding reagents create to immobilize hazardous constituents. Solidification refers to making a change in the physical properties of a waste. The result- desired changes usually include an increase of the compressive strength, a decrease of permeability, and encapsulation of hazardous constituents.

Stabilization at the other end, refers to chemical changes of the hazardous constituents in a waste. The desired-goal changes include converting the constituents into a less soluble, mobile, or toxic form by adding additional materials. S/S treatment involves mixing a jointed reagent into the contaminated media or waste. Binding reagents commonly used include cement, cement kiln dust (CKD), lime, lime kiln dust (LKD), limestone, fly ash, slag, gypsum and phosphate mixtures, and a various-kind number of proprietary reagents. Due to the great variation of waste constituents and media, a mixing material, design should be conducted on each type of waste. Most mix designs are a blend of the inorganic binding reagents listed above. Organic-blending have also been tried as well. These include asphalt, thermoplastic, and urea- formaldehyde. Organic binding reagents are rarely used in commercial scale due to their high cost compared to inorganic binders.

S/S is an effective treatment wide variety of organic and inorganic contaminants present in contaminated soil, sludge and sediment. The ability to effectively treat a wide variety of contaminants within the same media is a key reason why S/S is so frequently used in the remediation. Adding to the versatility of S/S treatment is the fact that contaminated material can be treated in-situ (in place) or ex-situ as already segregated waste or excavated material.

GN Desanding Unit for Construction

except solids control system for gas and oil drilling, GN solids control also designs and manufactures mud recycling system for other sorts of drilling, for example horizontal directional drilling, CBM, Tunneling, geothermal power drilling and piling. GN Desanding Plant is really a special mud making clear system for mining, piling, and horizontal directional drilling created by GN based on clients’ needs. This technique includes a working capacity of 120m3/h. This technique is made to consist of 2 stages of solids control and clarification procedure. For any compact structure, this technique combines a shale shaker along with a desander right into a desander mud cleaner whose model is GNZY753E-Y1S. First level separation is as simple as a shale shaker, and 2nd level is as simple as a desander.

The dwelling of GN Desanding Plant is proven in Fig 1 to Fig3, including mud treating tank, GNZY753E-Y1S Desander mud cleaner, GNSB6×5A-12J Centrifugal Pump, light, electric control and ladder, handrail, pathway and pipeline. This drilling mud system has compact structure and rational layout, and it’s simple for installation & dissembles.

The underside deck from the double deck shale shaker with 25 mesh screens is perfect for first stage cleansing treatment. When mud transferred towards the bottom deck for process, the solids whose dimensions are bigger compared to holes on screens is going to be released out, while fluids will mix the screens then fall into the mud tank. Then, the mud is going to be shipped towards the cyclones with a sand pump for more solids removal. Solids from the desander cyclones will fall on top deck with 40 mesh screen after which be released out. The liquid is going to be released in to the arranging tank through overflow pipes. Floating ball will close the pipeline once the mud reaches enough high, then the drilling mud after processed will flow out of the discharge port.
