Oil casing details

Different types of casing used in the oil extraction: Surface oil casing protects the drilling well from shallow water and shallow gas layers, support wellhead equipment, and maintains the weight of other layers of casing. The technical oil casing separates the pressure of different layers so that the drilling fluid can flow normally and protect the production casing. To install the anti-burst device, anti-leakage device, and liner in drilling. Reservoir oil casings channel oil and gas from subsurface reservoirs. Used to protect drilling wells and stratify drilling mud. When the oil casing is produced, the outer diameter is usually 114.3mm to 508mm.

Protect drilling wells from contamination by shallow water and shallow gas layers, support wellhead equipment, and maintain the weight of other layers of casing.

Reservoir Oil Casing - Channels oil and gas from subsurface reservoirs. Used to protect drilling wells and stratify drilling mud. When the oil casing is produced, the outer diameter is usually 114.3mm to 508mm. According to SY/T6194-96 "Petroleum Casing", it is divided into two types: short threaded casing and its coupling, and long threaded casing and its coupling.
