Mud cleaner is the second class in the drilling fluid system, separate the drilling fluid which is disposed by the first class. Mud cleaner is made of a group of hydrocyclone, a shale shaker and the shunted tubes. The upper is a group of hydrocyclone, the under part is a detail shale shaker.
The process of the mud cleaner disposed the drilling fluid divided into two steps. The first step; the drilling fluid is separated into the over flow and the bottom flow with the different density, the over flow return the drilling fluid circulating system, the bottom flow drop on the detail shale shaker.
The second step; the high density bottom flow is divided into two parts by the detail shale shaker, one part is the barites and the particles which is less than the mesh through the screen, the other part is the particles which is bigger than the mesh is eliminated by the screen, usually the screen is between 100mesh and 325 mesh, the 150 mesh is widely used.
Compared with the Deserter and the Desander, the mud cleaner have the characteristics of the throughput is big, out faster, the structure is compact and it is easy to operate and maintain, Integrated the advantages of the hydrocyclone and shale shaker, it can quickly remove the harmful solid phase in the drilling fluid, improve the performance of the drilling fluid , meet the requirements of the new process of the high pressure jet drilling.
