Oil casing is the lifeline to maintain the operation of the oil well. It is mainly used for the drilling and transportation of oil and gas Wells, and for supporting the well wall during the drilling process and after the completion of the well, so as to ensure the drilling process and the normal operation of the whole well after the completion.
Oil casing is mainly used for drilling of oil and gas Wells and transporting oil and gas. Due to different geological conditions, the underground stress state is complicated, and tensile, compressive, bending and torsional stress act on the pipe body, which puts forward higher requirements on the quality of casing itself. If the casing itself is damaged for some reason, it can lead to reduced production or even abandonment of the entire well.
