Solids control is a technique used in drilling rig to separate the solids in the drilling fluids that are crushed by the drill bits and carried out of the well surface. Normally drilling rig solids control system consist of five stages, including mud tank, shale shaker, vacuum degasser, desander, desilter, decanter centrifuge. Drilling fluids flow into the shale shaker directly after it returns to the surface of the well, and the solids that are removed by the screen would be dischanged out of the tank, and the drilling fluids with smaller solids would flow through the screen into mud tank for further purification. A centrifugal pump would sucks the shaker-treated fluids up to the desilter or mud cleaner for further purification. And vertical slurry pump is used to pump the drilling fluids up to the centrifuge,and mud pump would pump the drilling fluids from mud tank into the borehole after it is treated by centrifuge. And the circulation system would continue. The number of the mud tanks that are needed on the drilling rig depends on the depth of the well, and also the mud demands of drilling. Nomally the shale shaker and vecuum degasser and desander are mounted together on the same mud tank as the first tank at the oilfield, while desilter and centrifuge on the second tank. and also the drilling rig would has other different tank as reserve tank,emergency tank, etc. Kosun Is thet professional manufacturer of Solids Control System in China, KOSUN is a vital part of the world hydrocarbon exploration and production industry, as well as one of top three solids control equipment suppliers in China, which offers its products for CNPC, CNOOC ,HH, Gazprom, RG, etc .
