Why do we need to use solids control equipment in oil drilling engineering

I believe everyone knows that drilling fluid is the blood of the entire oil drilling system, and drilling fluid is very expensive. The solids control system can effectively separate the large cuttings, barite and other large solids from the wellhead back to the ground, and the treated drilling fluid can be reused. The solids control of oil drilling is to process and recover the drilling fluid returned to the surface through the solids control system or part of the solids control equipment. This reduces drilling costs and is good for the environment.

Now, the solids control equipment used in oil drilling solids control mainly includes: mud Shale Shaker, desander, desilter, horizontal screw centrifuge, mud cleaner, vacuum deaerator, liquid gas separator, mud agitator, jet mixing device, electronic ignition device, mud gun, screw conveyor, sand pump, shear pump, etc. At the same time, it is widely used in industries such as ore sorting, coal washing, sludge dewatering and starch separation.

The role of drilling fluid:

(1) Balance (control) formation pressure. Prevent blowout and lost circulation, and prevent the formation fluid from polluting the drilling fluid.

(2) Balance the rock side pressure of the well wall to form a filter cake on the well wall to seal and stabilize the well wall. Prevent pollution of oil and gas reservoirs and collapse of well walls.

(3) Clean the bottom of the well and carry cuttings. Keep the bottom of the well clean, avoid repeated cutting of the drill bit, reduce wear and improve efficiency.

(4) Cooling and lubricating the drill bit and drill string. Lower the temperature of the drill bit, reduce the wear of the drill tool, and increase the service life of the drill tool.

(5) Suspended rock cuttings and weighting agent. Reduce the sedimentation speed of cuttings to avoid sand sticking.

(6) It can sink sand and rock debris on the ground.

(7) Effective transmission of hydraulic power. Transmit the required power of the downhole power drilling tool and the hydraulic power of the drill bit.

(8) To bear part of the gravity of the drill pipe and casing. The buoyancy of the drilling fluid on the drilling tool and casing can reduce the load of the lifting system during tripping.

(9) Hydraulic crushing of rocks. The high-speed jet formed by the drilling fluid through the nozzle can directly break or assist in breaking the rock.

To sum up, in the oil drilling solids control project, drilling fluid is the blood of the whole system. If the solid particles in the mud are too large or too much, it may cause blowout and sticking, which is not conducive to controlling the speed and cost of drilling. However, the solid particles in the returned drilling fluid are separated by the solids control system to achieve solid phase control, which is conducive to stabilizing the stability and performance of the drilling fluid. It is more conducive to the speed of drilling. And can reduce the cost of drilling, which is conducive to environmental protection.
