Special oil pipe is mainly used for drilling oil and gas Wells and conveying oil and gas. It includes an oil drilling pipe, oil casing, and pumping pipe. The oil pipe is mainly used to connect the drill collar and transfer the drilling power. The oil sleeve is mainly used to support the good wall during the drilling process and after good completion, so as to ensure the drilling process and the normal operation of the whole oil well after well completion. The pumping pipe mainly delivers the oil and gas from the bottom of the oil well to the ground.

Oil casing is the lifeline to maintain the oil well operation. Due to the different geological conditions, the underground stress state is complex, and the comprehensive action of pulling, pressure, bending and torsion stress acts on the tube body, which puts forward high requirements for the quality of the casing itself. Once the casing itself is damaged for some reason, it may lead to the whole well production reduction or even scrap.

According to the strength of the steel itself, the casing can be divided into different steel grades, namely J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc. Different good conditions and well depths have different steel grades used. The casing itself is also required to have corrosion resistance in the corrosion environment. In places with complex geological conditions, the casing is also required to be resistant to extrusion performance.

Cangzhou Shenlong pipe is committed to the research and development and production of petroleum casing, screening pipe, and non-standard mechanical automation equipment, with complete product specifications and design, the company has strong production equipment and process, mature technical force, complete testing equipment, perfect quality assurance system.
