Abstract: The problem of site selection evaluation for salt cavern gas storage arises along with the rapid development of salt cavern gas storages. Based on the classification of the influence factors and the analysis of site selection for salt cavern gas storage, Analytic hierarchy process is used to build a layer structural model. Using expert investigation method, the importance weights of 18 influence factors are obtained. Then taking the advices of the experts on salt cavern gas storage building and the related research results into consideration, index suitability standards and synthetical evaluation standards of site selection evaluation for salt cavern gas storage are put forward. Combined with the importance weights of 18 influence factors, a formula is developed to calculate the synthetical appropriate value P of site selection. The results provide a feasible method and theory for the construction of salt cavern gas storage in China. Finally, this method is used to evaluate the suitability of building salt cavern in Yunying salt mine. The result is consistent with the expert opinions, which shows that this method is reasonable.

Key words: site selection evaluation, salt cavern gas storage, analytic hierarchy process
