Abstract: The wellbore of Jintan Gas Storage faces more failure risks than conventional natural gas wellbore due to its salt rock creep, frequent fluctuations of injection-production pressure, and abundant groundwater, which makes their safety evaluation and control requirements hard to be met by the conventional evaluation methods and conclusions. Herein, 10 specific risk factors of the wellbore of Jintan Gas Storage, including frequent fluctuation of injection-production pressure, alternating load, abundant groundwater and salt rock creep, were identified based on the geographical conditions of Jintan Gas Storage and the actual operation state of the wellbore. Meanwhile, the fault tree of Jintan Gas Storage wellbore was established with consideration of the possible failure modes caused by various risk factors, and the structural importance of wellbore was calculated and ranked. The results show that the maximum risk factor of wellbore failure in Jintan Gas Storage is the frequent fluctuation of injection-production gas pressure, which is significantly different from the sour environment of conventional natural gas wells. Among the 10 identified risk factors specific to the wellbore of Jintan UGS, 5 unique risks are ranked in the top 10 of the structural importance of the bottom event, which indicates that the failure risk of the wellbore of Jintan Gas Storage mostly comes from its own operating characteristics and geographic location. Finally, targeted measures for wellbore risk control of Jintan Gas Storage were put forward based on the management of conventional natural gas wellbore.
