Underground gas storage serves as a critical facility for natural gas peak shaving and strategic reserves. The injection-production string faces safety risks such as buckling, erosion, and vibration under cyclic loads, temperature variations, and complex wellbore conditions. Based on traditional dynamic analysis, this paper focuses on the dynamic effects of alternating loads by establishing a three-dimensional string dynamics model to systematically investigate vibration characteristics, stress responses, and fatigue life. The research findings aim to provide a theoretical basis for the safety evaluation and parameter optimization of gas storage injection-production strings.
