Casing pipe is a large diameter mild steel pipe, to play a fixed oil and gas wells or borehole wall effect. Well casing is inserted into the hole with cement to prevent the borehole and borehole collapse of rock separated, and to ensure that drilling mud circulation, so that drilling exploration. Oil extraction process used in different types of casing:

Surface Casing: Protecting drilling, to avoid being affected by pollution of shallow aquifers and shallow gas, wellhead equipment, support and maintain weight casing of the other layers.

Technology Casing: to separate the different levels of pressure, so the amount of normal drilling fluid flow and protect the production casing. For the installation of anti-burst in the drilling equipment, leak-proof devices and tail pipes.

Oil tube casing: the oil and gas from subsurface storage layer to export, for the protection of drilling, the drilling mud layer. Production casingScience Articles, usually 114.3 mm OD to 508 mm.
