Recently we finished production of one set of solids control system to India, including shaker tank and decanter centrifuge tank system. This is a 5 phase separation mud tank system for 1500HP oil drilling rig. The working principal is as below:

1） 3 units of shale shaker as the first phase cleaning to separate the big solids bigger than 100 microns from the drilling fluids, it can be used for both water based mud and oil based mud or synthetic oil based mud. The shaker screen installed on the shale shaker is composite material frame shaker screens comply with API RP13C.

The possem belly is installed behind the 3 units of shale shaker as drilling fluids distribution box and collect the drilling fluids from the mud gas separator or from the elevated manifold directly.
2) desander cone is the second phase cleaning to separate the cut point below 45 microns. The fluids with solids below 45 microns will drop into the mud tank compartment. The 2# centrifugal pump suck the drilling fluids from this compartment and feed to 4 inch desilter cone.
3) desilter cone is the third phase cleaning to separate the cut point below 25 microns the fluids below 25 microns will drop into the desilter compartment and the submersible slurry pump will suck the mud from this compartment and feed to GNLW452C decanter centrifuge.

4) middle speed decanter centrifuge is the fourth phase cleaning to separate the cut point 5~7 microns for barite recovery.
5) high speed decanter centrifuge is the fifth phase cleaning to separate the solids 2~5 microns for high gravity solids, especially when the drilling fluids has been reused for several years, the fine solids is accumulated a lot and it can not be reused again, then the high speed decanter centrifuge is required to lower the solids content.
