The configuration requirements for KOSUNs drilling rig solid control system depend on the depth of the well. Equipment selection may vary slightly for the same well depth in different regions, but the differences are not significant. Generally, the selection is based on the model of the drilling rig, ranging from ZJ20 to ZJ90. Typically, for ZJ30 and below, only three levels of solid control equipment are required, namely: drilling fluid shale shaker, desander, and desilter. For ZJ30 and above, a five-level purification equipment configuration is used, including: drilling fluid shale shaker, vacuum degasser, desander, desilter, and drilling fluid centrifuge. Mud tanks are essential as carriers and commonly used sizes include 95000x2300x2100mm and 125000x2400x2300mm. The number of mud tanks
