Types of oil casing

Different types of casing used in the oil recovery process: surface oil casing – protects the drilling well from contamination by shallow water and gas formations, – supports the wellhead equipment and maintains the weight of other layers of the casing. Technical casing – separates the pressure in the different layers to allow proper flow of drilling fluid levels and to protect the production casing. – To allow for the installation of anti-fracture devices, leak prevention devices and tail pipes in the drilled well. Oil Formation Casing – To move oil and gas out of the reservoir below the surface. – Used to protect drilling wells by layering the drilling mud. Oil casing is typically produced with an outside diameter of 114.3 mm to 508 mm.

Technical oil casing – separates pressures at different levels to allow proper flow of drilling fluid amounts and to protect production casing. – To allow for the installation of anti-fracture devices, leak prevention devices and tail pipes in the drilled well.
Oil Formation Casing – To move oil and gas out of the reservoir below the surface. – Used to protect drilling wells by layering the drilling mud. Oil casing is produced with an outside diameter usually from 114.3 mm to 508 mm.
Types and packaging of oil casing are divided into two types according to SY/T6194-96 “Oil Casing”: short threaded casing and its coupling and long threaded casing and its coupling.
