[0003] However, in the above-mentioned series of sieve types, the theoretical and practical results have shown that, without increasing the effective sieving area, that is, without increasing the space structure of the entire sieve box, the effective separation surface is affected by the use of a flat layered sieve structure. Due to the limitation, the space for increasing the processing capacity is basically extreme, and it is difficult to make a major breakthrough; the exciting force is the only driving force for passing through the mesh, and the separation mode of a single vibration, even if the overall size is increased, due to the special fluid properties of the drilling fluid, The parameters (excitation frequency and excitation force) of the vibration motors currently on the market do not meet the most suitable separation parameter requirements, which affects the processing capacity; the traditional vibrating screen is open for separation, and it is not convenient to equip with cuttings. The processing device and cuttings are discharged in the open air, and the environmental protection effect is not good; the performance of the traditional vibrating screen is single, and the screening operation link of the vibrating screen is completely independent from the entire drilling circulation system, without any feedback and intelligent links. Vibrating screen screening treatment, missed the best time to grasp the drilling conditions in time

Description
Technical field: [0001] The invention relates to the field of solid phase control of drilling fluid in oil and natural gas drilling construction, and also relates to industrial fields such as chemical industry, mining, food, and medicine that require material screening and transportation, especially the drilling fluid in oil and natural gas drilling development projects. Shaker. Background technique: [0002] Oil drilling vibrating screen is one of the key inertial vibration mechanical equipment used for solid-liquid separation of drilling fluid in drilling engineering. In order to continuously improve the screening efficiency of vibrating screens, various types of inertial vibrating screens have been developed at home and abroad, but they are all researched on changing the working mode of the screen box and increasing the effective screening area. The usual vibrating screen is a single-layer or multi-layer general-purpose plane, or a wave-shaped or other-shaped general-pur...
