Abstract: The construction of an underground gas storage cavern that meets design requirements is a complex systematic engineering project. Currently, there is limited analysis of the factors influencing nitrogen-assisted solution mining for salt cavern gas storage in China, and a systematic, intuitive analytical methodology has yet to be established. Based on field data from a gas storage facility in North China, this study establishes a three-level hierarchical structure of influencing factors for nitrogen-assisted solution mining using the Analytic Hierarchy Process (AHP). A computational model was developed to analyze the weight of each influencing factor, and the weight values were determined. The calculations reveal that the top six factors with the highest weights affecting the cavern construction results are, in descending order: cavern size design (0.1246), salt layer characteristics (0.1145), wellbore structure (0.0969), lithological features (0.0857), QHSE management system (0.0794), and on-site gas-liquid interface monitoring (0.0772). These six factors account for 57.83% of the total weight, representing the majority of the influencing factors. In contrast, the bottom three factors—drilling crew experience, personnel training, and wellhead procedures—have relatively low weights, collectively contributing less than 5% of the total. On-site construction efforts should prioritize the top three factors: cavern size design, salt layer characteristics, and wellbore structure. Additionally, detailed formation evaluation, enhanced on-site safety management, comprehensive and accurate gas-liquid interface monitoring, and optimized circulation design are critical aspects of current nitrogen-assisted solution mining operations. The findings of this study provide a reference for guiding on-site operations to achieve rapid, stable cavern construction and effective cavity shape control during nitrogen-assisted solution mining.
