During the operation, the drilling fluids containing amount of cuttings will be purified step by step to remove harmful solids and rematched to achieve proper viscosity and composition.The treated drilling fluids will be good enough for drilling operation again.
One of the most critical roles of this mud is as a lubricant. Drilling causes tremendous friction, which can damage the drills or the formation being drilled. Drilling mud cuts down on the friction, lowering the heat of drilling and reducing the risk of friction-related complications. The mud also acts as a carrier for the materials being drilled, with material becoming suspended in the mud and then being carried up the drill to the surface.
Drilling solids control equipment is the precondition to maintain the mexcellent drilling mud property which is the premise to prevention of underground accident, protection of oil layer,inprovement of drilling rate and reduction of drilling cost.Therefore,all the drilling rigs needs the assistance of solids control equipment for safe and effective operation.However,the performance of solids control equipment will directly affect drilling rig operation quality.Installed at the top of closed mud tanks,the drilling fluids solids control system is an combination of drilling purifaction equipment where drilling shale shaker, vacuum degasser, desander, desilter, mud cleaner,and decanter centrifuge are involved, and auxilairy solids control equipment including mud agitator, centrifugal pump, jet mud mixer and etc.
