Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells or wellbore. It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take place The oil casing is a steel pipe used to support the well wall of oil and gas wells to ensure the normal operation of the whole well during drilling and after well completion. Several layers of casing shall be used for each well according to different drilling depth and geological conditions. Cement shall be used for cementing after casing is put into the well. It is different from tubing and drill pipe and cannot be reused. It is a disposable consumable material. Therefore

api l80 13cr oil casing and tubing Tubing is mainly used to provide oil and gas flow passage during production of oil and gas wells. For flowing wells, due to the large inner diameter of the casing, the casing is directly used for production. Due to the density difference, pressure drop and expansion, the liquid flows up rapidly, causing the liquid to slip, resulting in the ineffective utilization of the downhole elastic energy. Running tubing with smaller OD and ID during production can...
