Oil casing is a steel pipe used to support the wellbore 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 casing according to different drilling depths and geological conditions. After the casing is put into the well, cement cementing should be used, which is different from tubing and drill pipe, and cannot be reused, and is a one-time consumable material. Therefore, the consumption of casing accounts for more than 70% of all OCTG. Casings can be divided into conduits, surface casings, technical casings and oil casings according to their use.
We can provide multiple oil casing according to customers' order.
