摘　　要：在含裂隙的岩盐中建造地下天然气储库工程必须研究裂隙岩体的气体渗流规律,以确保地下储气库工程安全运行,防止天然气渗漏。提出了岩体和裂隙的变形场与天然气渗流场的耦合模型,并建立了有限元分析的数值解法,在建设地下天然气储库确定气库的运行气压时可提供一些依据,对评价天然气储库的稳定性有参考意义。It is necessary to study the seepage law of gas for building the underground natural gas storage in fractured rock salt so as to insure the natural gas storages to work safely, keep natural gas form seepage. This paper puts forward a coupled mathematical model for the seepage field of natural gas and the deformation field of rock and fractures, and establishes the numerical solution of finite element analysis, can provide some bases to determine the operation gas pressure of underground natural gas storage constructed in rock salt, also can provide the reference to evaluate the stability of underground natural gas storages.
