The drilling mud decanting centrifuge is installed on top of a relatively taller mud tank. The drilling mud from bore hole flows through shale shaker, desander, desilter and was transfer to the decanter centrifuge to remove the find solids particles in it. The mud after the treatment of the decanter centrifuge are considered to be clean and can be reused back to the drilling hole.

The Selection of Decanter Centrifuge

For petroleum drilling mud treatment, we have both weighted and unweighted fluid. Then, centrifuge selection and configuration will not be the same. The well drilling depth is relative with fluid treatment.
 

Petroleum mud centrifuge has 3 types in total. We can classify it as large capacity centrifuge, high speed centrifuge, and barite re-circulation centrifuge. They have their own features and edges. We can adopt them on certain occasion.Due to different drilling conditions and well depths, sometimes we need configure or combine different types of centrifuges together to get ideal performance and save petroleum drilling cost and get more benefit.

Drilling Mud Decanter Centrifuge Installation

The installation site of centrifuge should be convenient for discharging base flow and recycling overflow. About the current level drilling fluids solid control system, the storage tank of desilter and mud cleaner treating fluid can also act as the suction tank of centrifuge, and the storage tank which recycling overflow must have agitator.

When using the centrifuge to recycle the barite of weighted drilling fluids, the separated base flow should be re-injected to the drilling fluids recycling system, because the base flow contains little liquid and is difficult to flow, it is hard to mix with drilling fluids, so the effect of agitator is very important, in other words, the mud tank which recycling barite base flow must contain has stirring apparatus. If the separated base flow is discarded through chute, the angle of inclination of chute will be 42°at least, and convenient for the waste flowing.
