Water-based mud waste treatment system
Jul 29, 2025
Against the backdrop of the continuous growth of global energy demand and increasingly strict environmental protection requirements, the oil drilling industry is facing unprecedented environmental challenges and transformation opportunities. As an indispensable component of drilling engineering, water-based mud, after fulfilling its functions such as wall protection, slag-carrying and cooling, often turns into difficult-to-handle waste, becoming a long-standing and intractable problem plaguing the industry. With nearly three decades of technological accumulation and innovative breakthroughs, Xi 'an KOSUN has successfully developed a series of efficient and intelligent water-based mud waste treatment systems, addressing industry pain points and providing cost-effective green solutions for global drilling enterprises.
Water-based mud, as the most commonly used circulating medium in drilling engineering, often becomes a difficult-to-handle waste after fulfilling important functions such as protecting the borehole wall, cooling the drill bit, and carrying rock cuttings due to the mixture of a large amount of drill cuttings, chemical additives, and formation materials. The traditional treatment methods are confronted with multiple predicaments: direct discharge will pollute soil and water sources and endanger the ecological environment; Simple landfill, however, occupies a large amount of land resources and poses a long-term risk of seepage. However, the natural sedimentation method is inefficient and cannot meet the high-intensity operation requirements of modern drilling engineering.
Meanwhile, the drilling industry itself is also confronted with cost pressure and efficiency challenges. The traditional mud treatment methods often require a large amount of human and material resources, have a long treatment cycle, and affect the overall project progress. However, untreated mud cannot be recycled, leading to the continuous input of new materials and significantly increasing operating costs. How to meet environmental protection requirements while improving processing efficiency and reducing overall costs has become an urgent problem for drilling enterprises to solve.
Xi 'an Kosun has a profound understanding of industry demands. Through continuous technological innovation, it has successfully developed a modular, intelligent and efficient water-based mud waste treatment system. The system scientifically processes the cuttings and waste drilling fluid generated during drilling through a series of precise procedures such as collection, transmission, dosing and stirring, gel breaking and destabilization, and solid-liquid separation. Our technology not only meets the strictest environmental protection standards, but also converts waste into reusable resources, truly realizing the circular economy model of "turning waste into treasure".
Precise solid-liquid separation: By using advanced equipment such as vibrating screens and mud cleaners, the solid and liquid phases in the mud can be efficiently separated based on the differences in particle size and density. The solid-phase control accuracy can reach ≤5μm, ensuring the precision of the separation effect and laying a solid foundation for subsequent processing.
Resource recycling: After the separated liquid phase undergoes deep purification treatment and meets environmental protection standards, part of it can be directly reused in the preparation of drilling fluid, achieving the recycling of water resources and significantly reducing the cost of new slurry preparation.
Overall, the water-based slurry waste treatment process is a comprehensive systematic project, which requires close cooperation among multiple links to achieve the best treatment effect. Through scientific processing procedures, we can not only effectively reduce the impact of mud on the environment, but also achieve resource recycling and reuse, thereby promoting sustainable development.
