It is also called mud purification system and is suitable for the drilling process of 2000-7000 meters oil wells. The oil solids control system consists of 3 to 7 modular combined tanks. The oil solids control system is used to separate and process particles such as cuttings and mud and sand in the drilling fluid, maintain the performance of the drilling fluid, and store the circulating drilling fluid.

[0003] A Chinese patent application CN211666669U discloses a solid control device for oil drilling fluid, including a liquid-solid control tank, the top of which is fixedly connected to a liquid inlet, the bottom of which is connected to a liquid outlet, the left and right ends of the liquid-solid control tank are fixedly connected to support rods, the bottom of the outer surface of the support rod is movably connected to a sleeve, the inner side of the top wall of the sleeve is fixedly connected to four rollers, the bottom of the support rod is fixedly connected to a fixed plate, the left and right ends of the bottom of the fixed plate are fixedly connected to shock-absorbing springs, and the bottom of the sleeve is fixedly connected to a foot pad.

It also has a shock-absorbing function, effectively provides shock-absorbing protection for the device, is easy to use, and is suitable for various situations.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: in the existing petroleum drilling fluid solid control device, after filtering the petroleum drilling fluid using a filter plate, a large amount of impurities accumulate on the surface of the filter plate due to long-term aggregation, thereby reducing the filtering effect of the filter plate. At the same time, when the petroleum drilling fluid falls, it will have a certain impact on the filter plate, which can easily damage the filter plate and reduce the service life of the filter plate; therefore, a petroleum drilling fluid solid control device is proposed to address the above problems.
