Composition of Oil Casing

Oil casing primarily consists of a casing body, a casing sleeve, and a casing ring. The casing body is the primary component of the oil casing, a hollow steel pipe within the oil well, used to withstand wellbore pressure and support equipment such as the casing and drill pipe. The casing sleeve is a liner covering the casing body, primarily protecting it from scratches and abrasion by the drill bit. The casing ring is a metal ring used to secure the casing and drill pipe, ensuring safe operation.
