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.
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.
