Introduction of oil casing
Different types of casing pipes used in the oil production process: surface oil casing protection drilling, so that it can avoid the shallow water layer and shallow gas pollution, support the wellhead equipment and maintain the weight of the other layers of the casing. Technical oil casing to separate different levels of pressure, so that the normal circulation of drilling fluid and protect the production casing. In order to install anti blowout device, leak proof device and a tail tube in a well. Oil and gas are derived from the storage layer under the surface of the earth. For the protection of drilling, the drilling mud layer. When the oil casing is produced, the outside diameter is usually 114.3 mm to 508 mm.

Oil casing type and packaging according to SY/T6194-96 "oil casing" sub short thread casing and its coupling and long thread casing and its coupling two.
