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 effectively solve the above problems by allowing fluid to flow in the tubing. Therefore, running tubing is required during production of flowing wells. The downhole operation and production of flowing well and non flowing well can be completed by using various tools for tubing running.
The basic requirements of the tubing used for workover are: to comply with the safety and economic principles, to meet the technical requirements adopted during well completion, and to meet the requirements for corrosion resistance and operation measures after the well is put into production.
According to the manufacturing process, oil pipes can be divided into seamless pipes and electric welded pipes. Seamless pipe is a kind of forged steel pipe without welding seam, which is made of hot working steel. After pressing, stretching, heat treatment and other processes, it reaches the standard size of oil pipe, forming a seamless oil pipe series. Electric welding pipe is a kind of pipe with a longitudinal weld formed by resistance welding or electric induction welding without filler metal. The welding edges are squeezed together by mechanical pressure, and the standard size oil pipes are reached through heat treatment and other processes, forming a series of electric welding pipes.
