The mud circulating system has 5 grade purification equipment to achieve the mud purification. The five-stage solid control system is mainly used for complex well conditions and well conditions with high requirements. Usually, according to the actual needs of drilling operations, one or more stages of purification can also be used.
The rationality and scientific of the configuration of the solid control system directly affect the efficiency of drilling. If the design and selection are reasonable, the drilling efficiency can be greatly improved in actual work.
The mud tank of the five-stage solid control system is equipped with a centrifugal separation chamber, and the centrifugal separation chamber is equipped with a centrifuge. The drilling fluid is input into the centrifuge under the action of the screw pump. The centrifuge separates smaller particles (particle size of 2~15µm) from the centrifuge, which is the five-stage purification. The purified drilling fluid enters the circulation tank through the drilling fluid tank. The processing capacity of the centrifuge should be 5%~10% of the total displacement of the drilling pump.
Drilling fluid purification solid-control system is a requisite part in modern drilling. It will ensure the slurry of the normal circulation and stability in the process of drilling rigs. It contains mud tanks , shale shaker, desander & desilter or mud cleaner, centrifuge, sand pumps , vacuum degasser , gas-liquid separator, shear pump, mud agitator , mud gun , flare ignition device , shale shaker screen , jet mud mixer , etc.
