The core equipment of Solid Control System mainly includes the following five categories, which work together to achieve efficient separation and purification of solid particles in drilling fluid:
- Shale Shaker
As the first separation checkpoint of the solid control system, it filters large particle rock debris (usually>75μ) in the drilling fluid through a high-frequency vibrating screen.; m）， The processing capacity can account for over 50%, significantly reducing the subsequent equipment processing load. - Desander
uses cyclone separation technology to separate solid particles with a particle size of 40-75 m, and its conical cyclone achieves efficient separation of solid-liquid two-phase through centrifugal force field, often equipped with bottom flow density monitoring function.. - Desilter
As a supplementary equipment to the desander, it focuses on processing fine solid phases of 15-40μ m. It adopts modular design and can be integrated with the desander for installation, making it suitable for complex formation drilling scenarios.. - Centrifuge
Separate<10μ by generating a strong centrifugal force field through high-speed rotation (usually>3000rpm); The ultrafine particles and colloidal substances of m, as well as the recycling and reuse of weighting materials (such as barite), can achieve processing accuracy up to the micrometer level. - Auxiliary Equipment Matrix
- Agitator: Maintain uniform suspension of drilling fluid in the mud tank to prevent solid phase precipitation from blocking the pipeline system.
- Mud Tank: Provides storage and mixing space for drilling fluid, equipped with liquid level monitoring and temperature control systems.
- Sand Pump: Provides a stable power source for sand and mud removers, using wear-resistant materials to cope with high solid content conditions..
- Shear Pump: Optimize the rheological properties of drilling fluid, especially suitable for pre-treatment of polymer drilling fluid systems.
These devices are processed through a hierarchical process (vibrating screen→); Desander→ Mud remover→ The centrifuge is used to construct a complete solid-phase control system, which, when combined with an intelligent monitoring system, can achieve dynamic optimization of processing parameters to meet the performance requirements of drilling fluids under different formation conditions.
