Mud cleaning system is an indispensable part of modern drilling equipment. The related products belongs to solid control equipment, for example, submersible sewage pump. It can meet the normal circulation and stable performance of drilling mud in drilling process, and ensures drilling operations on the premise of safety, environmental protection and high efficiency. Dachuan slurry purification system is a new type of product based on the advantages of integrated solid control systems at home and abroad, combined with the actual needs of the drilling process. It consists of a vibrating screen, a vacuum deaerator, a desander, a desilter, and a centrifuge. Solid-control equipment components can realize the storage and deployment of drilling fluids, remove harmful solid phases, maintain the performance of drilling fluids, meet the requirements of special conditions such as drilling fluid circulation, weight increase, shearing and accident handling, and can effectively improve the drilling operations. Efficiency and safety. Convenient for roads, railways, and dragging at short distances from the wellsite.
