Solids control is a technique used in drilling rig to separate the solids in the drilling fluids that are crushed by the drill bits and carried out of the well surface. Normally drilling mud solids control system is consisted of five stages, including mud tank, shale shaker, vacuum degasser, desander, desilter, centrifuge. Shale shaker is used to separate the big solids with diameter above 75μm, and 45~74μm for desander, and 15~44μm for desilter. Sometimes desander & desilter are combined as highly efficient mud cleaner. When air enters into the drilling fluids, vacuum degasser is used to separate the air. If no air is found in the mud, the degasser will work as a big agitator. All these equipment are mounted on the top of the mud tank. After separating the solids, the clean mud will be pumped into the borehole again.

Solids control system is used to:

1. Remove harmful solid phase and keep the drilling operations going;

2. Keep the drilling process safe and prevent some accidents;

3. Reduce the energy consumption;
 

4. Reduce the pollution and protect the environment.

Solids control system is constituted of:

1. Three-in-one mud cleaner, drilling fluids shale shaker, vacuum degasser, desander, desilter;

2. Drilling fluids decanter centrifuge;

3. And the others, like, centrifugal pump, shear pump, mud agitator, mud gun, mud circulating tank and batching apparatus.

At home, there is not yet a wide variety of drilling mud shale shakers. Therefore, it is necessary to research and develop dry fine-mesh shaker, tracked non-shaker analytical apparatus, offshore drilling environment-friendly solids control equipment and versatile supporting mud circulating system to enrich the variety of domestic solids control equipment. Though, in recent years, great breakthroughs have been made in the study on domestic solids control equipment’s theory and their production & processing level, especially that in the study of theories like, working theories of drilling mud shale shaker and centrifugal cyclones, etc., which has reached or near to the world-class standards, there is still a long way to go between domestic and foreign equipment in terms of performance and lifespan, extending to the materials, processing technology, processing precision and quality of supporting generic devices ( such as, electric motor ). There is no high-pressure, large-engine solids control equipment available at home now.
