What are the environmental protection equipment of Tianrui Oilfield and what are their specific functions?

During oilfield production, large amounts of oily wastewater and drilling wastewater are generated. Direct discharge of these wastewaters would cause serious pollution, necessitating specialized wastewater treatment equipment. Oilfield environmental protection equipment is diverse, covering multiple fields such as drilling waste treatment, oily sludge treatment, oil and gas recovery, wastewater treatment, energy-saving power, and intelligent monitoring.

TR Solid Control, as an oilfield solid control equipment manufacturer, offers powerful solutions. For example, its crude oil dehydration equipment, wastewater treatment devices, and high-efficiency sludge separation systems utilize advanced filtration and clean energy technologies to reduce pollution emissions at the source and protect the natural environment to the greatest extent possible.

I. Core Equipment for Solid-Phase Separation

Drilling fluid shale shaker

As the "first line of defense" in the solids control system, it separates drill cuttings particles with a diameter of ≥74μm from the drilling fluid through high-frequency vibration and a graded screen, intercepting large solid waste particles and preventing them from entering downstream equipment and causing wear or blockage.

Tianrui products adopt a modular design, which is suitable for both onshore and offshore drilling scenarios, and can quickly remove harmful solid phases to maintain the rheological properties of drilling fluids.

Desander / Desilter (including combination cleaner)

Desander: Separates 44-74μm sand particles using centrifugal force via a hydrocyclone, reducing wear on drilling pumps, drill bits, and other equipment, thus lowering maintenance frequency and material consumption;

Desilter: Further separates 15-45μm sludge-sized particles, forming a "secondary purification" process in conjunction with a vibrating screen, ensuring that the solid content of the drilling fluid is controlled within environmental standards;

Modular cleaner: Integrates two types of hydrocyclones and a vibrating screen, featuring a compact structure and space-saving design. The hydrocyclones are made of wear-resistant polyurethane material, suitable for harsh working conditions such as high-pressure jet drilling.

Horizontal screw discharge centrifuge

This "ultimate purification" equipment for 2-5μm ultrafine particles uses high-speed centrifugal force to separate colloidal solid phases, precisely controlling the density and viscosity of drilling fluid.

It has a significant effect on non-water-based drilling fluids. The separated liquid phase can be directly recycled and reused, while the water content of the solid phase is greatly reduced, thus reducing the amount of hazardous waste generated.

II. Auxiliary Purification and Circulation Equipment

Vacuum degasser/liquid-gas separator: Removes dissolved harmful gases such as natural gas and hydrogen sulfide from drilling fluid, preventing gas intrusion that degrades drilling fluid performance and controlling volatile gas pollution;

Mud tank and mixing system: The sealed tank is equipped to store the purified drilling fluid, and the agitator prevents solid sedimentation, reduces the risk of liquid overflow from the tank, and achieves "zero spillage" temporary storage of drilling fluid;

Sand pump / shear pump: Provides power for drilling fluid circulation, ensuring continuous operation of the solids control system and improving overall purification efficiency.

III. Complete Environmental Protection System for Oilfields

Drilling mud purification system: Integrates shale shakers, desanders, centrifuges, and other equipment to form a "three-stage purification + circulation" closed loop, capable of removing over 90% of solid particles with a diameter ≥2μm;

Trenchless/Shield Tunneling Mud Recycling System: Designed for scenarios such as directional tunneling and shale gas extraction, it enables the reuse of mud, reducing wastewater discharge during construction by more than 80%.

For example: The mud not-landing system produced by TR Solid Control Company

Function: Achieve zero discharge of water-based and oil-based mud. Through equipment such as drying screens, centrifuges, and screw conveyors, the solid and liquid phases in the mud are separated. The solid phase, after drying treatment, can be reused (such as for brick making and road construction).

Features: Meets environmental protection requirements, reduces waste volume and transportation costs.

IV. Environmental Protection Functions of Oilfield Equipment

Drilling fluid recycling reduces resource consumption.

Multi-stage purification enables drilling fluid reuse, reducing the amount of fresh drilling fluid needed and lowering water and chemical consumption. Data shows that a highly efficient solids control system can increase drilling fluid recovery rates to over 95% and reduce single-well costs by 15-20%.

Solid waste reduction and harmless treatment

After separation, the drill cuttings are dried and processed. The oil content can be controlled at a low level, which complies with the "Pollution Control Requirements for the Comprehensive Utilization of Solid Waste from Oil and Gas Field Drilling", and can be used for well site paving or disposed of in accordance with regulations.

Reduce the discharge of waste slurry to prevent soil and groundwater pollution.

Equipment protection and indirect environmental benefits

Removing hard solid particles from drilling fluid extends the lifespan of equipment such as drill bits and mud pumps by more than 30%, reducing solid waste generated from equipment scrapping. Simultaneously, it reduces drilling fluid viscosity and density, increasing drilling speed and shortening drilling cycles, indirectly reducing energy consumption.

Multi-scenario pollution prevention and control

It is suitable for land, offshore and unconventional oil and gas extraction. In offshore drilling, it can prevent drill cuttings and oily mud from directly flowing into the ocean. In shale gas development, it solves the problem of purifying high-sand drilling fluids.

With increasingly stringent global environmental standards, TR Solids Control's oilfield environmental protection equipment provides effective solutions for the oil drilling industry, addressing complex issues such as wastewater treatment, air pollution control, and soil remediation. Green environmental protection is no longer just a slogan, but a guide for action. Oilfield environmental protection equipment is becoming crucial in ensuring a balance between energy extraction and environmental protection.
