Drilling Solids Control System Equipment For Oilfield

Drilling fluid solids control systems (mud purification systems) are the "blood purification centers" of oilfield drilling operations.  Through multi-stage separation technology, they remove rock cuttings and harmful solid phases from the drilling fluid, maintaining stable mud properties and enabling recycling, thereby significantly reducing drilling costs and environmental pollution.

Focused on the stability of drilling solids control systems, solids control equipment main functions is remove drill cuttings and solid particles from returned drilling fluid, maintaining key properties like density and viscosity, recovering valuable materials such as barite, eliminating hazardous gases, ensuring drilling safety, enabling cyclic reuse of drilling fluid, and reducing waste fluid discharge.

Components of Solids Control System Equipment

The efficient operation of the drilling solid control system relies on the coordinated cooperation of various functional devices.  Each piece of equipment performs its specific function, forming complete purification and treatment chain that meets the requirements for separating impurities of different particle sizes and maintaining the performance of drilling fluid.

1. Shale Shaker

   As the first-level equipment of the solid control system, it quickly separates large rock cuttings (>74μm) from drilling fluid through high-frequency shale shaker, preventing them from entering downstream equipment and causing wear or blockage.

   Technical Features：

   Multi-layer sieve design allows for adjustable separation of particle sizes.

   Explosion-proof motor drive, suitable for harsh working conditions.

   Modular structure facilitates quick screen replacement.

   TRZS584 series: Single machine processing capacity 140m³/h, vibration intensity 8.5G, screen box made of high manganese alloy steel, surface heavy-duty anti-corrosion coating, suitable for harsh working conditions.




2. Desander and Desilter

   Desander: Utilizing cyclone separation technology, it removes medium-sized sand particles ranging from 40 to 74μm.

   Desilter: Used for further processing of fine particulate impurities ranging from 15 to 40 μm.

   Features: The two can be used in parallel or series. The centrifugal separation has high efficiency and is flexibly adapted to different working conditions.

   TRCS series desander: Processing capacity up to 300m³/h, it can separate particles ranging from 15 to 74μm.

   TRCN series desilter: Utilizing advanced hydrocyclone technology, they separate particles ranging from 10 to 15μm.




3. Decanter Centrifuge

   Micron-sized solid and colloidal particles are separated using high-speed centrifugal force, producing low-solids drilling fluid.  The differential speed is adjustable to adapt to different mud properties, and the fully enclosed design prevents secondary pollution.

   TRLW355~600 Series: Drum diameter 355-600mm, maximum speed 3200rpm, differential maximum 40rpm.




4. Vacuum Degasser

   Remove harmful gases from drilling fluid to prevent well gushing or blowout. Vacuum Pump creates negative pressure inside the tank, causing the bubbles to burst and be discharged, ensuring the safety of well control.

   TRZCQ Series: Quickly removes gas from gas-contaminated drilling fluid using negative pressure separation technology, restoring mud properties and preventing blowouts.




5. Mud Agitator and Mixing Equipment：The agitator is installed on mud tank to provide continuous stirring and prevent solid phase settling; the mixing pump is used to quickly add chemical agents and maintain the stability of the mud properties.




6. Mud Tank：The multi-compartment design enables zoned storage of clean mud, waste mud and transition fluid, and supports closed-loop circulation. The tank integrates all solid control equipment and is equipped with auxiliary facilities such as liquid level gauges, pipelines and valves.
