The solid control system mainly consists of vibrating screen, vacuum degasser, sand remover, mud remover, centrifuge five-stage solid control and mud tank, and sand pump, agitator, submerged slurry pump, jet mixing device, liquid level scale, alarms, medicine tanks, sitting post room and other equipment, as well as aisles, floating platforms, guardrails, escalators, ladders and other attachments, as well as anti-explosive lighting and explosion-proof electronic control system. According to the customers' requirements, our company has designed the corresponding mud solid control system scheme for different specifications and high standard drilling rigs, such as ZJ20, ZJ30, ZJ40, ZJ50, ZJ70, ZJ80, ZJ90, etc., and produced the mud solid control treatment system with the corresponding treatment capacity, which is widely used in the drilling of oil and natural gas, the development of coal-bed methane, the development of shale gas, the development of trenchless engineering (directional traversing, pipe jacking, shield construction ), construction piling, geothermal wells, river dredging and other fields. From design, production, operation and service, we have won wide recognition from customers.
