Casing pipe
Product use: the oil casing is used to support the oil and gas well wall steel pipe, to ensure the drilling process and the normal operation of the whole oil well after completion. Several layers of casing are used for each well, depending on the drilling depth and geology. Cement is used for cementing after casing well. Unlike tubing and drill pipe, cement can not be reused and belongs to disposable consumption material. As a result, casing consumption accounts for more than 70% of all well tubing.
