Drilling Oil Based Mud Solid Waste Treatment Oil Sludge Centrifuge

Drilling oil-based mud solid-waste treatment

Oilfield drilling requires drilling oil-based mud according to the drilling depth and geological conditions. The mud's basic composition is oil, water, organic clay, and oil-soluble chemical treatment agent. OBM resists high temperature and calcium salt erosion, which is beneficial to the stability and lubrication of the well wall.

The mud features good performance and small damage to oil and gas layers, and wide application in various types of drilling platforms. However, the slag generated in the equipment of drilling solid control system (vibrating screen, centrifuge, and dryer) has seriously affected the environmental safety and must be treated in a harmless manner. After treatment, the oil content of the slag is less than 1% and the oil is further purified and reused.

The collected drilling OBM solid wastewater is subjected to high-speed stirring in proportion, and a suitable amount of demulsifier, active agent, and other additives are added, so that the oily water in the emulsified state is broken. The vibrating screen is used before separation to remove large particles of soil, sand, glass bottles, mineral water bottles, convenient bags, gauze, and other solid wastes, and then the high-efficiency LW series two-phase centrifuge is adopted to separate continuously the (oil + water) + slag. After heated by steam, the separated liquid phase enters the sedimentation tank, in which the supernatant is removed, and the liquid phase settled at the bottom of the tank is mixed with the slag phase separated by the centrifuge. The residual oil is recovered by the thermal desorption process.

Separation performance:

1,It can recover about 90% of oil (relating to demulsification effect, temperature, etc.);

2,The solid content of the liquid phase after separation can reach ≤5~8%;

3,The dryness of the slag phase after separation can reach 40 ~ 60%;
