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%;
