Solid Control System is a comprehensive equipment system used in petroleum drilling engineering to control the solid content of drilling fluid (drilling mud). Its composition can be divided into four core modules, and each module works together to achieve precise control of drilling fluid performance:
- 1. Solid phase classification processing equipment
- Shale Shaker: As a primary separation unit, it filters large particle debris (>75μ m) from drilling fluid through multiple layers of vibrating screens (usually 40-200 mesh), with a processing capacity of 50% -70% of the total system flow rate. It is equipped with screen angle adjustment and sand flushing nozzle system.
- Cyclone separation unit:
- Desander: It uses a 10-12 inch conical cyclone to separate solid particles with a size of 40-75 μ m, equipped with a bottom flow density sensor and pressure compensation device.
- Desilter: Integrated with a 4-inch micro cyclone group, it separates particles ranging from 15-40 μ m and features a modular design that allows for quick replacement of cyclone cores.
- Centrifugal processing unit:
- Decanter Centrifuge: Separate<10μ by using double drum differential rotation (differential range 0-30rpm); M ultrafine particles and colloids, equipped with variable frequency drive and torque monitoring system.
- High Speed Centrifuge: Specially designed to remove oil-based pollutants from drilling fluids, with a speed of over 6000rpm, equipped with gas seals and explosion-proof devices.
