Oil casing can be divided into different steel grades according to the strength of the steel itself, namely J55, K55, N80, L80, C90, T95, P110, Q125, V150, and so on. Different good conditions, well depth, and the use of steel grade are also different. The casing itself is also required to have corrosion resistance in a corrosive environment. In the place of complex geological conditions, the casing is also required to have the ability to resist collapse. Oil casing is the steel pipe used to support the wall of oil and gas Wells to ensure the normal operation of the entire well during the drilling process and after the completion of the well. Each well uses several layers of casing, depending on the drilling depth and geology. Cement should be used after the casing running. It is different from tubing and drill pipe, and can not be reused. It belongs to disposable consumption material. As a result, casing consumption accounts for more than 70% of total good pipe consumption. The casing can be divided into pipe, surface casing, technical casing, and oil casing according to the use.
