[0002] Drilling fluid is a general term for various circulating fluids that meet the needs of drilling work with their multiple functions during the drilling process. Drilling fluid is also called drilling flushing fluid. Drilling fluid can be divided into clean water, mud, clay-free flushing fluid, emulsion, foam and compressed air according to its composition. Clean water is the earliest drilling fluid used. It does not need to be treated and is easy to use. It is suitable for intact rock formations and areas with sufficient water sources. Mud is a widely used drilling fluid, mainly suitable for unstable rock formations such as loose, cracked, prone to collapse and block falling, and swelling and peeling when exposed to water. During the exploration and development of oil, a large amount of waste drilling fluid will be left at the drilling site. The degree of resource utilization and treatment is still a thorny issue in the field of the oil industry. There are many objectively difficult to solve difficulties in the solid-liquid separation technology of drilling fluid.
[0003] The desanders and desilters currently in use have poor on-site effects, with high moisture content in the solid phase outlet, frequent loss of drilling fluid at the underflow outlet, and the need for a high-power sand pump to supply drilling fluid. The life of the hydrocyclone is short. The nominal processing capacity of the desander and desilter is quite different from the actual processing capacity, resulting in some mud entering the hydrocyclone from the overflow outlet before it can be processed.
