Tunneling Mud System for China Market

The mud treatment is getting more and more important in tunneling project, not dumping. While as limit space, big capacity, the mud cleaning system for tunneling project is always a problem, especially when it is for the system used for the site.

2 sets 1500gpm mud system for domestic client HDD project are ready for delivery. The client used for tunneling project.  1500gpm mud system including below items: 1) 3 sets 500gpm treating capacity shale shaker: GNZS703E-DZ, totally treating capacity 1500gpm 2) 1 set 1500gpm treating capacity mud cleaner: GNZJ703E-3S16N. 3) One mud recycling tank with shale shaker & mud cleaner 4) One mud storage tank with mud agitator / mud gun to storage / mix clean mud ready for use.

In China, tunneling mud was always no need to handle very carefully, while all the cost including dumping, transportation, and water, chemicals, personnels are getting higher. Then it is more resonable to have the system to handle the drilling cutting mixture.

One of the important division for GN Solids Control is the underground construction, our main business in this division is  HDD, horizontal directional drilling mud recycling and mud mixing system, second is desanding equipment for bored pile foundation, third is the slurry separation plant for the Micro-Tunneling.GN have the slurry separation plant from120m³/h to even 1000 m³/h available. Either with single mud tank system or multi-tank system for drilling mud separation and drilling mud mixing.

Now GN can have all solutions for different tunneling projects.

GN Own Brand Shaker Screen used on GNZS Line Shale Shaker

GN Solids Control is an API qualified manufacture for drilling mud solids control equipment. Without doubt, the shale shaker model is one of the most important equipment in your production line, in the at the same time, shale shaker is the most essential primary solids control products that takes place in the function of separating the rough solids in the drilling mud as the first stage solids control equipment.
The perform of shale shaker to part ways the solids should supply credit to the mesh screen fixing on the shale shaker unit. By using different nylon uppers screen, the shale tremble unit could do splitting up process on different slurry. GN now has 3 major size shale shaker product, each of them is equipped with GN do it yourself designed and manufactured shaker screen. The shale shaker models are GNZS752, GNZS703 and GNZS 594, correspondingly fixed with 2 panel, 3 panel and some panel screens.

From the shale shaker model, we can discover some hints of the shape of the screen. The shaker screen used of the shaker product 752 is 750x900mm. This particular shale shaker is popular in some small capacity absolutely no dig drilling project in addition to core drilling solids eradication unit. Thus, this shaker model is also baby shaker. The shaker 703 will be fixed with screen dimensions of 700x1250mm; this shaker model is widely used throughout oil drilling and some huge capacity HDD project. In line with the model GNZS703, GN gives you the shaker model GNZS706 with 2 layers shaker deck, and 6 portions screen fixed. And the GNZS705 model is often used seeing that underflow shaker for a mud cleaner unit to further dried the solids discharged by cyclone units. While the shaker model GNZS594 is permanent 4 pcs screen having dimension of 585x1165mm. This specific model could be used as being a primary shaker in solids control system, and it can also generally be used as high R force drying shaker with waste cuttings drying system. What we need do is with two high power premium vibrators.
Guess through this article, the consumer would be easily to choose GN’s shaker screen if you already got GN’s shale shaker available. Besides, GN can also provide substitution screen for many other brands shale shaker that widely used on the market. Just let us know after getting the request for the shaker screen.

GN Drill Cuttings Solidification Unit to Africa

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.

Solidi cation and stabilisation generally requires the use of specialised accessories and actinic reagents. The processes absorb signi deceit abstracts administration upstream and after of the bond unit. Some decay streams may accommodate contaminants that can arrest the solidi cation/stabilisation processes.

For the solidication / stabilisation action to yield abode it is important to carefully adviser the decay produced at the rigsite for levels of alkali baptize and oil. This will advice to minimise the use of reagents and optimise the process, thereby abbreviation costs and the ecology impact.

Thus, it is with the accomplishment and ability that Scomi Oiltools has developed over the endure 20 years that allows us to, accommodate safe, amount e ective and environmentally complete solidi cation and stabilisation processes.

GN Drilling Cuttings Drying System For African Client

GN Solids Control already furnished more than 30 sets connected with drilling cuttings drying system to one of the largest company in Nigeria and all of these working well and pleased clients for long term get close to. Normally it will contains up and down cuttings dryer, decanter centrifuge, screw pump, screw conveyor, work platform and or mud tank to make a complete system, but depending on drilling situations and requirement, the clientele may change design down to drilling site requirement.

Key EquipmentsFor This African Clientele

3 sets of usable cuttigns dryer which will be accustomed to dry drilling cuttings from shale shaker, desander in addition to desilter. It is 30 to be able to 50 tons per hour ability with a 930 mm height tank body at 930 RPM rotating speed. Weather knife installed to help prevent screen block by h2o base drillingcuttings. The air chef's knife driven by one set of weather compressor and one set of twist pump will be used to remove outlet of dryer to support fluids flow out properly.

6 sets of adjustable speed decanter centrifuge to help recycle drilling fluids split up by vertical cuttings dryer at 2 to 5 microns by 0 to 3200 RPM rotating speed. The actual decanter centrifuge is fish hunter 360 mm bowl diameter along with 1270 mm long jar, there are tungsten carbide mosaic glass bolted on screw impeller to help it working extended time and easy for replace tungsten carbide tiles. VFD control panel is designed to change centrifuge speed max to 3200 RPM depending on working circumstances.

3 sets of providing pump for decanter centrifuge to feed fluids in to and 3 sets regarding pump for flush top to bottom cuttings dryer to help essential fluids flow out successfully. 18 sets of screw conveyor to transfer drilling cuttings amount different machine just about all cuttings box.
