The special oil pipe is mainly used for the drilling of oil and gas Wells and the transportation of oil and gas. The utility model includes oil drilling pipe, oil casing and oil pumping pipe. Oil drill pipe is mainly used to connect the drill collar to the drill bit and transfer drilling power. Oil casing is mainly used to support the well wall during drilling and after well completion, so as to ensure the drilling process and the normal operation of the whole well after well completion. Suction tubing mainly carries oil and gas from the bottom of the well to the surface.<\/p>\n\n\n\n
