Oil and gas drilling
Oil drilling mud:
Oil drilling mud, commonly known as drilling mud, plays a very important role in oil drilling operations.
Drilling fluid is the general name of various circulating fluids that meet the needs of drilling with its various functions in the drilling process. Drilling fluid is the blood of drilling, also known as drilling rinse fluid. Drilling fluid mud, mainly suitable for loose, crack development, easy to collapse and block, water expansion and spalling hole wall unstable rock.
Main functions:
The harsh environment of underground drilling operations facilitates the research and development of drilling fluids, which require the ability to perform a number of key tasks during drilling: suspension, pressure control, rock stability, buoyancy, lubrication, and cooling.
