Knowledge of oil casing as following:
Protection of drilling, make it avoid polluted by shallow layer and shallow gas.
Reservoir oil casing:
Protection of drilling, make it avoid polluted by shallow layer and shallow gas.
- the oil and gas are derived from the storage layer under the surface of the earth.
- protects the drilling, drilling mud layer.

Oil special pipe is mainly used for oil and gas well drilling and oil and gas transmission. It includes petroleum drill pipe, oil casing, tubing.
Different grade of steel used as well conditions, hole depth is different. In corrosive environment also requires casing itself has corrosion resistance. While the complicated geological conditions also demanded that casing collapse resistance.
Any more details,please contact with me and i will offer help as much as we can.
