Describe the Components of the solids control system

The solids control system is composed of multi-stage purification equipment, auxiliary equipment and pipeline systems.  All levels of solids control equipment work in collaboration to achieve purification from coarse to fine.

The Components of Solids Control System

• Mud Shale Shaker:
  Primary Solids Control equipment is also the “first line of defense” of the solids control system. The large particle cuttings (with a particle size of ≥74μm) in the drilling fluid are separated by high-frequency vibration.
  The processing volume is usually 1.2 to 1.5 times the circulation volume of the drilling fluid, ensuring the efficient operation of subsequent equipment.
  mus shale shakers can be classified into linear shale shakers and elliptical shale shakers. elliptical shale shakers are widely used in deep Wells and horizontal well drilling. it features high screening efficiency and strong processing capacity.
• Desander:
  Secondary Solids Control equipment. The desander adopts the principle of hydrocyclone to separate sand particles with a diameter of 20-74μm from the drilling fluid. It is usually used in conjunction with shale shakers. The sand grains separated by the cyclone fall into the small vibrating screen below to further recover the drilling fluid. ​
• Desilter：
  The third level in the solids control system. The sludge separator separates fine sludge particles of 10-20μm. The shaker screens of the deslimer is generally configured with 120 mesh. The sand removal cyclone has a smaller diameter and higher separation accuracy. It can effectively reduce the mud content of drilling fluid and maintain the stability of rheological properties. ​
• Decanter Centrifuge：
  Four-level deep Solids Control equipment. Solid-liquid separation is achieved by utilizing centrifugal force. Centrifuges are mainly used to separate ultrafine particles of 5-10μm. It is suitable for precision drilling scenarios with extremely high requirements for drilling fluid performance. It is mainly used for shale gas development and deep-sea drilling. It can enhance the reuse rate of drilling fluid.
