In the Beijing-Tianjin-Hebei region, there is a huge gap in the capacity of natural gas peak regulation. Due to the influence of fault development and complex structure in Jizhong Depression, the evaluation of fault sealing ability is the top priority in the feasibility study of reservoir construction, but it lacks theoretical support and evaluation criteria. In this study, by calculating the shale gouge ratio, fault plane normal pressure, fault activity rate and fault growth index of the main fault in the gas-bearing structure of Jizzhong depression, to explore the quantitative characterization of fault sealing property value and the correlation of oil reservior, gas reservoir and aquifer. Then the parameter boundary of fault sealing ability is established, and the quantitative evaluation standard of fault sealing ability of gas storage is obtained. It provides theoretical support and practical guidance for the selection and evaluation of new gas storage sites in Jizhong depression. 2021 IEEE.
