Different types of casing used in oil extraction: Surface oil casing protects the well from contamination of shallow water and gas zones, supports wellhead equipment, and maintains the weight of other layers of casing. Technical oil casing separates pressures at different levels to allow for the normal flow of drilling fluids and to protect the production casing. To install anti-burst devices, anti-leak devices, and tailpipes in the drilling well. Reservoir oil casings carry oil and natural gas from reservoirs beneath the earth’s surface. Used to protect drilling wells and layer drilling mud. When producing oil casing, the outer diameter usually ranges from 114.3 mm to 508 mm.

According to SY/T6194-96 “Petroleum Casing”, oil casing types and packaging are divided into two types: short-threaded casing and its couplings and long-threaded casing and its couplings.
