Different types of casing used in the oil production process: Surface oil casing protects the wellbore from contamination by shallow water and shallow gas layers, supports wellhead equipment, and keeps the weight of other layers of casing. Technical oil casing separates the pressure of different layers to allow the normal flow of drilling fluid and protect the production casing. To install anti-burst devices, leak-proof devices, and tailpipes in the wellbore. Reservoir oil casing guides oil and gas from the reservoir layer below the surface. Used to protect the wellbore and stratify the drilling mud. When the oil casing is produced, the outer diameter is usually 114.3 mm to 508 mm.

According to SY/T6194-96 “Oil Casing”, the types and packaging of oil casing are short threaded casing and its coupling and long threaded casing and its coupling.
