Oil Solids Control System
The oilfield solids control system is a specialized combination of equipment used for solids control in drilling operations. Through the synergistic action of core components such as shale shakers, desanders, desilters, and centrifuges, it achieves the graded separation and purification of solid particles in the drilling fluid.
This system effectively removes particles larger than 0.15 mm and solid matter larger than 0.07 mm, improving mud reuse rates, reducing overall drilling costs, and minimizing the risk of stuck pipe accidents caused by solid accumulation. Its closed-loop circulation design significantly reduces waste mud discharge, combining engineering efficiency with environmental value.
1. System Composition and Functions
Basic Components:
Shale Shaker: Achieves primary filtration of drilling fluid through high-frequency vibration, separating large solid particles larger than 0.15mm.
Desander: Employs cyclone separation technology to remove sand particles in the 0.07-0.15mm range.
Desilter: Further treatment of fine particulate impurities of 0.04-0.07 mm.
Centrifuge: Separates micron-sized solid phases and colloidal particles using high-speed centrifugal force.
Some drilling sites also add a degasser after the shale shaker to remove harmful gases such as H2S; this is what is commonly referred to as five-stage purification.
The solids control system adopts a modular design, which can flexibly adjust the equipment combination according to the working conditions such as drilling depth and formation characteristics.
2. Technical Parameters and Processing Capacity
Core performance indicators of the oilfield solids control system include:
(1)Maximum processing flow rate up to 500 m³/h, adaptable to deep drilling needs.
(2)Shale shaker screen mesh size range: 40-200 mesh, supporting quick replacement.
(3)Cyclone desander separation efficiency ≥95%.
(4)Centrifuge speed adjustable range: 2000-3500 rpm.
The system can remove 99% of ineffective solids from drilling fluid in stages, maintaining the stability of key parameters such as mud density and viscosity.
3. Application Scenarios and Advantages
This system is widely used in oil drilling, geological exploration, and other fields. Its technical advantages are reflected in:
(1) Reducing drill bit wear and extending instrument life through solid phase control.
(2) Reducing mud replenishment and saving 15%-25% of single-well operation costs.
- Reducing the risk of wellbore collapse and improving the safety of construction in complex formations.
- Environmental Value
Te oil solids control system adopts a closed-loop circulation process, achieving environmental benefits through the following methods:
(1) Centralized collection and treatment of waste solids, avoiding soil pollution.
(2) Increased circulating water reuse rate to over 85%.
(3) Reduced waste slurry discharge by approximately 200-400 m³ per well operation.
- Equipped with a mud recovery device, hazardous waste components can be separated for compliant disposal.
