Types of oil casings

Different types of oil casing used in oil production: Surface oil casing protects the well from contamination by shallow water and shallow gas layers support wellhead equipment and maintain the weight of other layers of casing. Technical oil casing separates pressure at different levels so that drilling fluid flows properly and protects the production casing. To install an anti-burst device, anti-leakage device, and tailpipe in the well. Reservoir oil casings conduct oil and gas from subsurface reservoirs. Used to protect drilling and layer drilling mud. When oil casing is produced, the outer diameter is usually 114.3 mm to 508 mm.

Reservoir Oil Casing - Leads oil and gas from subsurface reservoirs. Used to protect drilling and layer drilling mud. When oil casing is produced, the outer diameter is usually 114.3 mm to 508 mm.

According to SY/T6194-96 "Petroleum Casing", there are two types of oil casing and its packaging: short-threaded casing and its coupling, and long-threaded casing and its coupling.
