After the extra-long holiday in history, clients are happy to see GN Solids Control come back to work and started fabrication for equipment. Just recently, after days of hard work, GN Solids Control just finished the manufacturing of a complete mud cleaning system for China Coalbed Methane Drilling Company.

All drillings need drilling mud as media to protect the drilling bid and to bring out the cuttings. Based on different mud components and different job site condition, and also the drilling depth, the mud cleaning equipment are not exactly same. But following equipment are always in need:

1. Shale shaker: shake shaker is the physical separation, which plays the most important role during the separation work. By using the suitable mesh size screens, the shale shaker move out the largest portion of cuttings from the drilling mud. In this system, there are 2 sets of shakers, totally serve 240cbm per hour capacity. An efficient shale shaker can separate out all particles larger than 100 microns by using suitable shaker screens.

2. Hydrocyclones. The mostly common used cyclones are 10 inch cones and 4 inch cones, respectively called the desander cones and desitler cones. The desander cones are used to move out particles larger than 40 micrions and desilter cones are used for move out particles larger than 20 microns. In this mud system, for the coalbed, the client decide to use the desilter cones only.

3. Decanter centrifuge. Decanter centrifuges are more and more used in different kinds of separations for the particles from 2 to 5 microns. Not all projects are using centrifuges at jobsite, although most of mud should be further treated by a decanter centrifuge. Some service companies are using centrifuge in a separate yard like professional mud treatment service companies.
