High Speed Oilfield Oil Base Mud Treatment Oil Sludge Centrifuge

With the global attention to the natural environment and the soundness and perfection of environmental laws and regulations in various countries, higher requirements have been placed on the disposal of waste on the drilling site, and a new concept of cutting waste while drilling does not fall. The cuttings while drilling treatment system not only can solve the on-site environmental problems, but also can recycle the waste generated by the on-site solid control system, maximize the recovery of useful mud, and carry out the re-treated drilling waste. Concentrated curing/drying/incineration to reduce damage to the environment.

The oil-based mud waste treatment system independently designed and developed by ZK Separation Technology Co., Ltd. which consists with high-speed frequency conversion centrifuge, cutting dryer, mud tank assembly, cuttings box, screw pump, screw conveyor. And other equipment, easy to transport while drilling.

Technical descriptions of the centrifuge

★ Extremely low infrastructure investment and good on-site operating environment

Compared with the conventional filter-type equipment (plate-and-frame filter, belt machine, etc.), the high-performance centrifuge is compact and efficient, covering only about a third of land, needless of auxiliary gas source, high-pressure water, and with simpler pipe structures at the inlet and outlet. Moreover, the operation environment is more humanized, and the skid-mounted integrated device has the characteristics of compact structure, convenient installation, low requirements for infrastructure, and convenient movement. The centrifuge is widely used in the harmless treatment of oily sludge in oilfield drilling.

★ Stable operation, low failure rate, and low maintenance cost

Compared with the filter type equipment, the centrifuge does not require any filter cloth or filter screen, so as to avoid the trouble of clogging and of replacing the filter cloth. The operation and maintenance costs of the equipment are low.

★ Modular design, easy to operate

Our design philosophy: To lower the requirements on the skills, educational level, and labor intensity of operators, and realize one-button start and stop of the control system, fault self-diagnosis, and safety self-protection.

★ Operator configuration and labor intensity

The high-performance centrifuge is an automatic and continuous working mode for feeding-separating-slag (liquid) discharging. The whole process requires no human intervention. Multiple sets of equipment require only one inspector (in conjunction with other positions). Unlike frame and plate-and-frame filter, the slag discharging process does not require manual cutting, greatly reducing the labor intensity of the operator.

Separation performance:

1, About 80~90% oil can be recovered (relating to oil density, demulsification effect, temperature, etc.), and the recovered oil can be used for refining purpose after further purified by the flottweg separator;

2, The water content of the oil phase after separation can reach ≤3 ~ 5%;

3, The dryness of the slag phase after centrifugation can reach 40 ~ 60%, and its total volume is reduced by over 80% compared to that before
