A KIND OF PREMIUM THREAD CONNECTION TUBING DEVELOPMENT USED IN HIGH PRESSURE GAS WELL
As progressing of oil and gas exploitation techlogy, severe condition wells, such as deep wells, high pressure oil and gas wells, highly deviated wells and corrosion wells, etc. are exploited. Above all, sealing performance of pipe string which can directly influence on the exploitation safety for high pressure gas, is the most important index during premium thread connection tubing and casing development. A kind of premium thread connection tubing product which can serve in high pressure gas well and combined load condition, is introduced in this paper. Metal-to-metal seal leads to its sealing integrity despite high gas pressure. Furthermore, optimum design such as thread shape, parameter and surface treating, lead to the connection structural integrity despite tension load, the galling integrity despite repeated make-up, and enhanced corrosion-resistant capacity of whole connection. FEM simulation and full scale test are applied in this development, results prove that: this kind of premium thread connection tubing gets an predominant high gas pressure sealing performance in combined load condition.
