An oil casing is a large-diameter pipe that fixes the walls or holes of oil and natural gas wells.

Usage: The oil casing is inserted into the wellbore and fixed with cement to prevent the wellbore from separating the rock formation and the wellbore from collapsing, and to ensure the circulation of the drilling mud to facilitate drilling and production. Oil casing is a steel pipe used to support the walls of oil and gas wells to ensure the normal operation of the entire oil well after the drilling process and completion.

Each well uses several layers of oil casing according to different drilling depths and geological conditions. Cement is used for cementing after the oil casing is downhole. Unlike oil pipes and drill pipes, it cannot be reused and is a one-time consumable material.

Oil casing can be divided into conduit, surface casing, technical casing, and oil layer casing according to usage.
