Nowadays, how to make use of drilling mud to meet the purpose of safe production, environmental protection, as well as economical and effective application has been a major subject of drilling production.
Common problems take place in oil and gas drilling fields
Drilling mud , namely drilling fluids is known as the "blood" of drilling and it is a kind of mixture of oil, water, organic clay and oil-base mud chemicals, which can effectively reduce the friction resistance, reduce the accident rate and improve the quality of well bore. Drilling mud is widely used in horizontal Wells and vertical Wells drilling. In recent two years, there are more and more drilling cases using oil-base mud, accordingly the subsequent drilling expenses growth and safety environmental protection problems have been increasingly outstanding. In addition, accounting from lacking of oil-base mud cutting processing equipment, drilling engineering companies is very passive in international project bidding. As a result, the drilling waste management system http://www.kosun.us/drilling-waste-management/ is in urgent use and development.
Drilling waste treatment equipment working procedures and basic prionciples
Abandoned drilling mud from the mouth of the well directly access to the device. And through its sealing strip type pipe, screw conveyor transfers waste drilling mud into cuttings dryer. Then the screen mesh by high-speed rotating and filter by cutting dryer, then the vast majority of the dry cutting slips down by another screw conveyor and discharged from the first mouth exit. The remaining liquid mud is fed into the centrifuge by feed pump and is processed again. Then the separated drilling cuttings will eventually be fine cuttings and is isolated from the second sand mouth. At the same time, the treated sludge by reinjection pipelines to the mud tank is recycled again.
And above described processors simply focus on a short circle of drilling mud disposal treatment within the drilling mud reuse processing. And the necessary equipment is vertical centrifuge, screw conveyor, screw pump as well as decanter centrifuge.
