It includes petroleum drill pipe, oil casing, oil tubes.
Oil drill pipe is mainly used to connect the drill collar and bit and drilling.
oil casting pipe is mainly used for drilling and well completion on the wall of support, to ensure the drilling process and the normal running of the whole well after completion.
While oiltubesleading to the well at the bottom of the oil and gas transmission to the ground.
According to the strength of the steel itself casing can be divided into the different steel grade, namely J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc. Well conditions, hole depth is different, have different grade of steel used. In corrosive environment also requires casing itself has corrosion resistance. Where the complicated geological conditions also demanded that casing collapse resistance.
