Drilling Mud Decanter Centrifuge is Widely Used in Separating Smaller Solid

Decanter centrifuge can be used on drilling site to separate suspended solids with particle diameter larger than or equal to 2μm and treat the drilling mud and fluids. It serves as the last-stage drilling mud solids control equipment, applicable for treating unweighted and weighted drilling mud.

When used to treat unweighted drilling mud, centrifugal separation process is very effective for drilling mud with low solid phase. Decanter centrifuge of large treating capacity is suitable for such purpose. It can deal with 23~45m3 liquid each hour, processing 3~4t solid phase. The decanting centrifuge separates the drilling mud into underflow and overflow. The large quantity of useless solid phase contained in the underflow is discharged into waste pool, and the precious liquid phase is returned into the drilling mud tanks. Since the drilling mud with low solid phase can bring immeasurable economic benefits, the drilling mud decanter centrifuge is more and more widely used to remove the solid phase in unweighted drilling mud.

Decanter centrifuge is widely used in drilling mud separation to separate smaller solid particles after the equipment processing such as drilling mud shale shaker and drilling fluids mud cleaner or desander and desilter. Usually, decanter centrifuge is equipped with screw pumps or slurry pumps to feed drilling mud to the centrifuge. Correct and proper operation and good condition make sure that drilling mud decanter centrifuge operate ordinarily with high performance. Next, in this essay, expedient measures to maintain drilling fluids will be closely described by steps.
