surface High Quality Seamless Steel Oil Casing Pipe- protecting the well from shallow water and gas pollution and supporting the wellhead equipment and maintaining the weight of other layers of casing.
Technical oil casing pipe - the pressure that separates different layers so that the amount of drilling fluid can flow normally and the production casing can be protected.
Reservoir casing pipe- the process of exporting oil and gas from reservoirs below the surface. It is used to protect drilling and separate drilling mud. In the production of petroleum casing, the outer diameter is usually 114.3 mm to 508 mm.
