Oil Casing Type

- Jan 17, 2019-

Different types of casing used in oil extraction: Surface oil casing protects the well from contamination by shallow water and shallow gas, supports wellhead equipment and maintains the weight of the other layers of the casing. The technical oil casing separates the pressure at different levels so that the drilling fluid is properly circulated and the production casing is protected. In order to install the anti-burst device, the leakage preventing device and the tail pipe in the drilling. Oil-in-oil casings export oil and gas from the subsurface storage. Used to protect the well and stratify the drilling mud. When producing oil casings, the outer diameter is usually 114.3 mm to 508 mm.

Oil layer oil casing - Exports oil and natural gas from the subsurface storage layer. Used to protect the well and stratify the drilling mud. When producing oil casings, the outer diameter is usually 114.3 mm to 508 mm.

The types and packaging of oil casings are classified into SY/T6194-96 "oil casing" short-threaded casings and their couplings and long-threaded casings and their couplings.
