READ: Fluid circulating system has been frequently mentioned in previous passages surrounding solids control technology, and are to be more illustrated in this one. The circulating process is completed when the drilling fluids circulates through hydrocyclone desander, mud desilter, vacuum degasser and decanter centrifuge, through the discharge manifold in solids control module to mud pump, through its water lines into the centrifugal pump.
It is known that drilling processes are: fluid-purification process, fluid circulating process, mud dosing process, mud concocting process, mud weighting process, automatic irrigating process, etc. Among them, fluid circulating system has been frequently mentioned in previous passages surrounding solids control technology, and are to be more illustrated in this one.
The centrifugal pump, arranged inside mud cabin, suctions cleaned mud with the aid of injection pump. The drilling fluids travels out under the high pressure of AC variable frequency centrifugal pump, through dual high pressure pipelines to vertical pipe valve group standing on the drill floor after the divergence via valves in mud cabin, through the double tribble, hose, upper driving device(or swivel), inner chamber of drill string to drill bit in the well hole. Then, the high-pressure drilling fluids jets into the well bottom and carries solid phase back to wellhead via the annular space between drill string and casing pipes, out from the horn mouth under the turntable, through the mud pipelines below drill block to the horizontal mud cabin, and through the vertical mud cabin and the treatment of drilling mud shale shaker into the tank. Afterwards, the circulating process is completed when the drilling fluids circulates through hydrocyclone desander, mud desilter, vacuum degasser and decanter centrifuge, through the discharge manifold in solids control module to mud pump, through its water lines into the centrifugal pump.
