Mud linear vibrating screen: as the first-class solid control equipment for drilling fluid treatment, it is used to remove other harmful solid particles such as rock cuttings in the drilling fluid. Different number of screens are selected for drilling fluid to control the size of the particles, mainly solid particles larger than 74 microns.

1. Mud linear vibrating screen: as a first-class solid control equipment for drilling fluid treatment, it is used to remove other harmful solid particles such as cuttings in the drilling fluid. Different numbers of screens are selected for drilling fluid to control the size of the particles, mainly solid particles larger than 74 microns.
2. Cyclone separator (desander, desilter): the desander is the secondary purification equipment of drilling fluid, and the desander mainly removes sand particles larger than 44~74 microns. The desilter is mainly used for three-stage purification of drilling fluid, and the desilter mainly acts on argillaceous solid particles above 15-44 microns. The micro cyclone can also be selected according to the actual situation of the drilling fluid, which is mainly used to separate the mud solid particles above 2~4 microns.

3. Drilling fluid centrifuge: its function is to control the clay particles in the well fluid, control the solid phase of the drilling fluid, remove the solid phase content of the non-weighted drilling fluid, and recover the barite in the weighted drilling fluid. Drilling fluid centrifuge mainly acts on solid particles of 2~4 microns.

4. Vacuum degasser: Vacuum degasser mainly removes the gas invading drilling fluid, which does not belong to the scope of solid control. However, due to the fact that gas invasion is very harmful to the specific gravity, viscosity and density of drilling fluid, degassing devices are usually used.
Oil drilling solid control equipment and solid control system are the equipment and system for processing and recovering the drilling fluid (mud) returned to the ground from the wellhead. The solid control system can effectively separate the large drill cuttings, barite and other large solid particles in the (mud) returned to the ground from the wellhead, and the treated drilling fluid (mud) can be reused. This reduces the cost of drilling and contributes to environmental protection.
