Different types of
casing pipe used in oil extraction: Surface oil casing protects the well from being contaminated by shallow water and shallow gas layers, supports wellhead equipment and maintains the weight of other layers of casing. The technical oil casing separates the pressure at different levels so that the drilling fluid can flow properly and protect the production casing. In order to install anti-burst devices, leak-proof devices and tail pipes in the drilling. Reservoir oil casings direct oil and gas from reservoirs below the surface. It is used to protect drilling and to layer drilling mud. When producing oil casing, the outer diameter is usually 114.3 mm to 508 mm.

Types and packaging of petroleum casings are divided into two types: short-threaded casing and its coupling and long-threaded casing and its coupling according to SY / T6194-96 "Petroleum casing".
