Oil and casing Pipe description
Oil and casing Pipe is the steel pipe used to support the wall of oil and gas Wells to ensure the normal operation of the entire well during the drilling process and after the completion of the well. Each well uses several layers of casing, depending on the drilling depth and geology. Cement should be used after casing running. It is different from tubing and drill pipe, and can not be reused. It belongs to disposable consumption material.
Oil and casing Pipe application
Oil casing is mainly used to support the well wall during drilling and after completion, so as to ensure the drilling process and the normal operation of the whole well after completion. The pumping pipe mainly transfers the oil and gas from the bottom of the well to the surface.Oil casing is a kind of large diameter pipe to hold oil and gas well walls or holes. Casing is inserted into the hole and secured with cement to help separate the rock formation and prevent the hole from collapsing, while keeping drilling mud circulating to facilitate drilling and production.
