20'' Casing Pipe

The oil casing is a large-diameter pipe that acts as a fixed oil and gas well wall or well bore. The casing is inserted into the well bore and fixed with cement to help the well bore separate the formation and prevent the well bore from collapsing, while drilling the mud to circulate for drilling.

Steel grades for oil casings: H40, J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc. Casing end machining form: short round thread, long round thread, trapezoidal thread, special buckle, etc. It is mainly used for oil well drilling mainly for the support of the well wall during and after the completion of the drilling process, and the normal operation of the entire oil well after completion of the drilling process.


Application of 20'' Casing Pipe:

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.
