What solids control equipment will be used in oil drilling?

Mud linear vibrating screen: As a solid control equipment for drilling fluid treatment, its function is to clean up cuttings and other harmful solid particles in the drilling fluid. The drilling fluid uses different numbers of screens to control the size of the particles, mainly the solid particles larger than 74 microns. 

Cyclone Separator (Desander, Desilter): Desander is a secondary purification equipment for drilling fluid. Desander is mainly used to clean sand larger than 44~74 microns. The desilter is mainly used to purify the drilling fluid. The desilter mainly acts on the muddy solid phase 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 muddy solid phase particles above 2~4 microns.

Drilling fluid centrifuge: The 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. The drilling fluid centrifuge mainly acts on the solid phase particles of 2~4 microns.

Vacuum degasser: The vacuum degasser is mainly to clean up the gas that invades the drilling fluid, which does not belong to the scope of solids control. However, since gas invasion has great harm to the specific gravity, viscosity performance and density of drilling fluid, degassing devices are usually used.

Oil drilling solids control equipment and solids control system are equipment and systems for processing and recycling the drilling fluid (mud) returned from the wellhead to the ground. The solids control system can separate large drill cuttings, barite and other large solid particles from the wellhead back to the surface (mud), and the treated drilling fluid (mud) can be reused. Thus, the cost of drilling is reduced, and it is beneficial to environmental protection.

Depending on the drilling depth, the number of equipment equipped is different. If the drilling is relatively shallow, such as 2 or 3 kilometers, the general mud shaker, mud cleaner, mud mixer, mud gun, screw conveyor, and sand pump are almost the same.

For deeper wells, centrifuges, shear pumps, screw pumps, jet devices, vacuum degassers, liquid-gas separators, and ignition devices (these two are just in case, a bit like a fire extinguisher) ).

Specifically, the solid control manufacturer can be equipped with a plan according to the drilling situation, and the equipment inside is also optional, saving costs.

Common solids control equipment in oil drilling includes: mud shaker, mud cleaner, vacuum degasser, desander, desilter, medium speed centrifuge, high speed centrifuge, mud mixer, mud mixing tank, jet Mixers, sand pumps and other pumps, etc.

The drilling solids control equipment can be integrated with the drilling solids control system. It can be matched with ZJ20-70 drilling rig to work at the same time.
