Oil drilling solids control system is the use of physical methods to remove the harmful solids phase in drilling fluid to improve the performance of drilling fluids and store the drilling fluid.The reasonable configuration and use of oil drilling solids control system is important to improve drilling degrees,protect oil-gas layer and prevent the blowout, adjust the drilling fluid performance and reduce drilling costs.

The design of high-pressure oil drilling solids control system can provide the best performance for the drilling operation. Each high-pressure mud sand pump can both run at the same time,but can also run separately according to the drilling operation and maintenance requirements. The discharge pipe drawn from the high pressure mud sand pump should be the type of discharging automatically,otherwise, the mud is easily deposited and blocked in the discharge tube, resulting in over pressure of high-pressure mud sand pump.
 

Normal delivered drilling mud from the tank through the high-pressure mud sand pump sand,the pump transport the mud to high-pressure mud standpipe manifold after pressurizing drilling mud,it will carried by the hose through the drill pipe and arrived at shaft bottom,and then return to carry cuttings from the annulus inflow to the bell, into the wellhead return mud tank,shunt by box diversion, drilling mud return to mud tanks after the drilling mud shale shaker remove large drilling cuttings,and then processed by vacuum degasser, cyclone desander, desilter and return to drilling mud tank for recycling use. At the same time, the high-pressure t manifold mud pump's outlet is also connected with the throttle manifold for drilling control and operations.

With the development of drilling technology, the performance of the drilling fluid has become an important symbol of scientific drilling. Drilling fluid is the blood of the drilling process, its role is: to clear and suspend drilling cuttings and suspended the bottom, so that it be carried to the ground and set; cooling the drill and drill rig; forming a low permeability filter cake and cover the wall; controlling formation pressure; bearing part of the weight of the casing and drill rig;protecting and providing downhole wellbore information; reduce oil consumption; transferring the water power to the drill bit;preventing drill rig corrosion. So oil drilling solids control systems' role are also increasingly prominent for drilling fluid.
