Ordinary carbon steel casing is suitable for conventional oil and gas Wells under medium pressure and temperature conditions, such as shallow land Wells and medium-depth oil and gas Wells. With the continuous development of oil and gas exploration and exploitation in the direction of depth, under harsh working conditions such as high temperature and high pressure and complex geological conditions, casing needs to withstand more and more external pressure. As a result, casing weight increases and hole diameter decreases. The critical crush strength of high collapse resistance oil casing is higher than API casing with the same steel grade and wall thickness, which can improve the collapse strength without increasing the steel grade and wall thickness, reduce casing weight, and reduce the cost of oil and gas Wells. Because Baotou iron ore raw material contains rare earth elements, its high collapse resistance casing has a significant advantage in the industry.<\/p>\n","protected":false},"excerpt":{"rendered":"
