Application: Casing Pipe is widely used for fastening oil and gas well wall or borehold, with bigger diameter than tubing, including surface casings, technical casings and oil layer casings.
Casing Pipe is used to support the oil, gas wells of steel pipe, in order to ensure the drilling process and the completion of the entire well after the normal operation. Each well has several layers of casing depending on the drilling depth and geology. Casing down to use cement cementing, it and the tubing, drill pipe is different, can not be reused, a one-time consumption of materials. Therefore, the casing of the total consumption of more than 70% of the wells. Casing according to the use can be divided into: catheter, surface casing, casing technology and oil casing.
