In oil drilling operations, the cleanliness of the drilling fluid directly impacts drilling efficiency, wellbore stability, and the service life of drilling equipment. As drilling depths and complexity continuously increase, traditional desanders and desilters struggle to meet the demands of high-efficiency purification alone. The drilling mud cleaner, as a comprehensive separation equipment integrating both desanding and desilting functions, has become an indispensable component of modern solids control systems. With deep research into drilling fluid solids control technology, Kosun has accumulated extensive experience in cleaner design, manufacturing, and application, providing reliable mud purification solutions for global oil and gas drilling projects.

The main purpose of the drilling mud cleaner is to further remove medium-to-fine drilling solids—typically particles sized between 20 and 74 microns—that the shale shakers failed to screen out. If these fine solid particles are not removed promptly, they can lead to increased drilling fluid viscosity and abnormal density, which in turn increases drill bit torque, accelerates wear and tear, and may even cause safety risks such as stuck pipe and wellbore collapse. The cleaner combines centrifugal separation and screening processes to efficiently remove solid phase particles without altering the essential mud properties, ensuring the mud circulation system maintains optimal flow properties and stability.

During the working process, the pre-treated drilling fluid first enters the hydrocyclone separation unit of the cleaner. High-speed rotation generates centrifugal force, forcing heavier solids outward. The separated upper liquid then undergoes secondary filtration via fine underflow screens, ensuring a cleaner discharge. Xi'an Kosun’s drilling mud cleaners feature optimized fluid dynamic structural design, offering low flow resistance, high separation efficiency, and overall stable equipment operation. They maintain continuous, efficient purification even under high solids loading conditions.

Compared to single-function equipment, the drilling mud cleaner offers significant advantages, including a compact structure, strong processing capacity, and convenient maintenance. It not only significantly reduces the load on subsequent centrifuges but also lowers the overall energy consumption of the mud processing system, extends the drilling fluid life cycle, and ultimately reduces drilling costs at the source. Kosun has incorporated modular design concepts into the equipment, allowing the cleaner to flexibly adapt to different solids control system layouts for both onshore drilling and offshore drilling platforms, ensuring easy installation, commissioning, and simplified maintenance.

Furthermore, Kosun has fully optimized material selection and process details. The main body of the equipment uses wear-resistant, anti-corrosion steel, and the hydrocyclones are made of high-molecular polyurethane for superior impact resistance and wear life. The screening section utilizes high-strength stainless steel composite screens, guaranteeing precise screening accuracy and stability during long-term operation. Certain models are also equipped with intelligent monitoring systems that provide real-time data on pressure, flow rate, and vibration status, offering precise data support to operators and further enhancing system safety and intelligence.

The stable operation of the drilling mud cleaner not only improves the purification efficiency of the mud circulation but also effectively protects the wellbore structure, reduces wear on drilling tools, and extends equipment lifespan, thereby achieving cost reduction and efficiency improvements while boosting drilling efficiency. With over thirty years of deep cultivation in the industry, Kosun consistently adheres to the development philosophy of "establishing a foothold with quality, leading with innovation." By continuously optimizing product performance and improving the after-sales service system, the company provides efficient, environmentally friendly, and economical drilling fluid cleaning solutions to global oilfield clients. In the future, Xi'an Kosun will continue to focus on solids control technology innovation, assisting the oil drilling industry in moving toward a safer, more efficient, and greener direction.
