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
