Oil casing is a large-diameter steel pipe that plays a role in fixing the walls or wellbore of oil and natural gas wells.
Usage: Petroleum casing is inserted into the wellbore and fixed with cement to prevent the wellbore from separating rock layers and wellbore collapse, and to ensure the circulation of drilling mud to facilitate drilling and mining. Oil casing is a steel pipe used to support the well wall of oil and gas wells to ensure the normal operation of the entire oil well during the drilling process and after completion.
Each well uses several layers of oil casing based on different drilling depths and geological conditions. Cement is used to cement the oil casing after it is lowered into the well. Unlike oil pipes and drill pipes, it cannot be reused and is a one-time consumable material.
Petroleum casing can be divided into conduit, surface casing, technical casing, and oil layer casing according to usage conditions.
