Working Principle of Drilling Waste Treatment Equipment

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.

The working principle of drilling waste treatment equipment
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.

With the enhancement of environmental consciousness. nowadays many more environmental regulations limiting or banning the discharge of various types of drilling fluids and associated drill cuttings globally. The drilling contractors started to utilize "zero discharge" or "ship to shore" drilling operations. In these operations, drill cuttings and associated waste fluids are collected on the rig in cutting boxes and then sent back to shore for disposal or treatment prior to disposal. Even when the discharge of drill cuttings offshore is still allowed. there is often now a requirement to collect and transport drill cuttings on the rig for secondary process such as vertical cutting dryer that will reduce the volume of drilling fluids associated with cuttings prior to discharge. In the drilling waste management or some similar works, screw conveyor or auger is a necessary part to convey materials from base ground to a higher position for further treatment.

Screw conveyer, commonly known as auger. It has horizontal, inclined and combined form, and it can be used with other transport devices, to accomplish combined transport, separate transport, mixing, blending, dehydration, compounding, discharging and stacking, etc. KOSUN Screw Conveyer is used in the drilling waste management for the drilling fluids or cuttings transportation.
