Drilling fluids circulating solids control equipment, as primarily aimed at controlling the solid content, must work together with drilling fluids purification device.

Increased solid content in drilling fluids will result in remarkably decreased mechanical drilling speed and even some drilling accidents, thus surging up the overal cost in well. Drilling fluids circulating solids control equipment, as primarily aimed at controlling the solid content, must work together with drilling fluids purification device. Experiments prove that 1% decrease in solid content will generate at least 10% boost of drilling speed, and the size of solid particles has inversely proportional relationship with their influence on drilling speed.

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.
