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
