How is the drilling waste management system working?

At present, foreign countries generally value the development of the oil industry drilling and completion technology, drilling waste disposal, from the beginning of the last century, the corresponding drilling waste is processing equipment and devices has been in the international advanced level.Drilling waste and Completion waste complex composition, vertical cuttings dryer of stability is particularly strong, vertical centrifuge deal with complex situations, which determines the current diversity of drilling sewage treatment plant in the world.

After the waste drilling mud cuttings from the wellhead back out, directly into the means by which a sealed strip-type pipe - delivered to auger,cuttings dryer, after drier and high-speed rotation of the screen filtration, drying vast majority of debris along another spiral conveyor from a sand discharge port, the remaining liquid slurry is pumped through the centrifuge, be subdivided, will eventually separate out the fine rock crumbs sand discharged from the second port. Meanwhile, after mud treatment through line reinjected into the mud tank again recycled.

In the oil exploration and production, the well field would leave a lot of waste. These wastes remain in the well field cesspools, waste solids due process is not complete, encountered rainy season, a lot of rain erosion, as cesspool leakage, overflow, flooding, etc., may have an adverse groundwater and surface water influence and threaten the surrounding ecological environment, and may even cause pollution accidents. In response to these harmful substances, how to take the appropriate drilling waste treatment technology to minimize the waste of environmental damage caused by drilling fluids, oil and gas companies is currently a very important job.
