API 5CT J55 casing is to maintain the oil well operation lifeline
|
|
API 5CT J55 casing casing casing factory scale, mainly used for oil, gas well drilling and oil, gas transmission. It includes pipe, oil casing drill. The tube is mainly used to connect the drill collar and drill bit and drill for oil drilling force transfer. Petroleum casing pipe is mainly used for supporting the wall during the drilling and completion, in order to ensure the normal operation of the oil well drilling and completion process. At the bottom of the well casing will be the main oil, gas transmission to the ground.
API 5CT J55 casing is to maintain the oil well operation lifeline. Because of the different geological conditions, the underground complex stress state, tension and compression, bending, torsion stress acting on the pipe body, it set a higher request to the casing itself quality. Once the casing damage due to some reason, may cause the whole well cut, even scrapped.
According to the strength of casing steels can be divided into different steel grade, i.e. API 5CT J55, K55, N80, L80, C90, T95, P110, Q125, V150 etc.. Well, the well depth is different, the different steel grade. In the corrosive environment also requires the casing itself has corrosion resistance. In the complex geological conditions where the casing collapse strength requirements with.
