The cuttings spin dryer (also known as the continuous screen centrifuge) is a highly efficient solid-liquid separation device, featuring an automatic feeding control function, and is widely used in the treatment of drill cuttings during drilling operations. This equipment effectively separates the liquid components contained in drill cuttings by applying high-intensity centrifugal force, thereby achieving a high recovery rate of drilling fluid, improving resource utilization, and reducing environmental impact.

During the development of shale gas, horizontal drilling operations generate a large amount of waste oil-based mud. If this type of slurry is discharged directly without proper treatment, it will not only cause serious pollution to the natural environment such as soil and water bodies, but also lead to a large waste of oil resources. At present, the centrifugation-distillation treatment technology initially applied in engineering still has problems such as high operating costs and low treatment efficiency. Therefore, Kexun Machinery is actively committed to developing efficient, economical and environmentally friendly processes for the treatment and resource recovery of waste oil-based mud, providing key technical support for promoting the large-scale green development of shale gas.

Kosun Machinerys HDD mud recycling system is dedicated to achieving efficient recycling and reuse of waste mud. It not only significantly reduces users operating costs and enhances economic benefits, but also effectively protects drilling rig equipment and reduces pollution to the surrounding environment. This system, through the collaborative operation of solid control equipment such as vibrating screens, desanders, desilters and mud cleaners, conducts multi-stage screening and purification treatment of drilling waste mud, ultimately achieving the recycling of mud. This system is an efficient mud treatment solution specifically developed for trenchless engineering. Its core objective is not to completely remove all solid substances, but to selectively separate useless solids such as drill

Solid particles in drilling fluids can be classified into two major categories: harmful solids and useful solids, among which cuttings are the most significant harmful solids. Throughout the entire drilling process, cuttings can significantly affect the physical properties of the drilling fluid, leading to an increase in its density, viscosity, dynamic shear force, water loss, mud cake thickness, abrasiveness, viscosity and flow resistance. In addition, cuttings can also cause damage to oil and gas layers, reduce the mechanical drilling rate, increase the torque of the turntable, and lead to complex downhole situations such as obstructions during drilling and lowering, stuck sticking, well leakage, and even blowouts. Meanwhile, the presence of a large amount of rock debris will also acceler

In industrial production and environmental governance, solid-liquid separation equipment is an important piece of equipment for enhancing efficiency, reducing costs and achieving green development. Solid-liquid separation technology is widely applied in fields such as oil drilling, municipal sewage treatment, mining, chemical engineering, and food processing, and is gradually becoming a must-have equipment on enterprise production lines. The core working principle of solid-liquid separation equipment is based on the mechanical characteristics of multiphase fluids. Through physical actions such as gravitational sedimentation, centrifugal force field, membrane separation, and medium screening, it achieves precise separation of solid-liquid two-phase systems. The essence of its technology lie

Drilling fluid centrifuges are indispensable equipment in oil drilling engineering. Their main function is to separate solid particles in drilling fluid to ensure the performance and quality of the drilling fluid. Selecting the appropriate drilling fluid centrifuge is of great significance in improving drilling efficiency, reducing drilling costs, and protecting the environment. I. Understand the basic types of drilling fluid centrifuges Drilling fluid centrifuges are mainly classified into the following types: Sedimentation centrifuge: It uses centrifugal force to make solid particles settle and separate in a high-speed rotating drum. Separation centrifuge: Through high-speed rotation, it separates liquids and solid particles of different densities. Filter centrifuge: Separates solids and

As a key unit of the mud purification system, the drilling fluid desander plays a cornerstone role in multiple industrial scenarios with its highly efficient solid particle separation technology.
It utilizes the principle of centrifugal force field to precisely remove sandy particles from drilling fluid that damage system performance, ensuring the reliable operation of core equipment and promoting the industrial model of resource recycling. The following are several application scenarios of drilling fluid desanders:

Amid the roar of oilfield development, drilling operations are advancing efficiently. However, the drilling waste that comes along with it has become a persistent problem plaguing the industry’s development – the traditional disposal methods are costly, environmental protection pressure follows closely, and the waste of resources is truly regrettable. How to break the deadlock? The drilling waste treatment technology developed by Xi ‘an KOSUN offers you a one-stop green solution!
