Drilling fluid circulating process is the basic process of drilling fluid solid control system, it is mainly according mechanical separation theory of solid control equipment and removing the harmful solid phase in drilling fluid.
Drilling fluid flow out of the well month through line pipe flow into distributor, the distributor can transport drilling fluid to two or three shale shakers respective or at the same time, after processed by shale shaker enter into desilting bin, the drilling fluid flow out from desilting bin through pipe line enter into desanding pin. The desilting pump absorb drilling fluid which in desilting pin, the drilling fluid is transported to desander by pipe line, the drilling fluid is processed by desander through flume enter into desilting pin, the drilling fluid is processed by desilter enter in to centrifugal pin. The vertical industrial pump of centrifuge suction drilling fluid of centrifugal pin, the drilling fluid is transported to centrifuge by pipe line, the drilling fluid is processed by centrifuge through flume enter into the store tank. Drilling pump absorb drilling fluid of store tank through pipe line is transport to well month. This is drilling fluid circulating process.
Dosing process of drilling fluid
Drilling fluid dosing process is the auxiliary process of drilling fluid solid control system, its main function is adding chemical agent to drilling fluid, use the principle of chemical precipitation, eliminate the harmful solid phase, it also can improve drilling fluid performance and decrease the complex condition in bottom well. Preventing leakage and leaking stoppage. Improving the steady of the wall of well. Increasing mechanical drilling speed.
