Petroleum casing is also called special oil pipe, which is mainly used for the drilling of oil and gas wells and the transportation of oil and gas. It includes drill pipe, casing pipe, and oil pumping pipe. Drill pipes are mainly used to connect drill collars and drill bits and transmit drilling power.
Casing pipe is mainly used to support the well wall during drilling and after completion to ensure the progress of the drilling and the operation of the entire well after completion. The pumping pipe mainly transports the oil and gas from the bottom of the oil well to the ground. Oil casing is the lifeline to maintain the operation of oil wells. Once the casing pipe is damaged for some reason, the output of entire well may be reduced or even scrapped. According to the strength, the grade of casing pipe can be divided into J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc. Different well conditions and depths have different steel grades. In a corrosive environment, the casing pipe is required to has corrosion resistance. In places with complex geological conditions, the casing pipe is required to has anti-collapse performance.
