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. In different good conditions, and well depth, the steel grade is also different. In an environment of corruption, the casing itself is required to have an anti-corruption function.

It is also required that casing should have an anti-collapse function in the complex geological premises. Oil casing is a steel pipe used to support the good walls of oil and gas Wells to ensure the abnormal operation of the entire well after the drilling process and completion. Depending on the drilling depth and geology of each well, how many layers of the casing should be applied? Casing after the well to take cement is different from tubing, and drill pipe, can not be repeated application, and belongs to a one-time consumption of data. As a result, casing consumption accounts for more than 70% of the total oil well pipe. The casing can be divided into pipe, surface casing, skill casing, and oil casing according to the application situation.
