| 摘 要： | 盐穴储气库作为油气储气库的主要类型之一，已经在发达国家普遍采用。随着“西气东输”工程的进行以及天然气工业的不断发展，我国将会有更多的盐穴地下储气库建成并投入运行，因此怎样科学合理地分析盐穴储气库的稳定性已显得越来越重要。利用国际上著名的有限差分软件FLAC^3D，对金坛盐矿某区老腔1号井、2号井建库完成后的腔体稳定性以及腔体蠕变规律进行了数值模拟，模拟结果表明，储气库在运行期间，流变会引起溶腔体积的减少，溶腔内压对储库的体积减少有直接的作用。并且利用该软件确定了储气库的运行压力在6MPa-14．5MPa之间，溶腔的体积缩小率在22％以内，为储气库的修建及管理提供了指导依据．

| Abstract: | As a type of gas or oil storage, salt-cavern gas storage has been adopted widely in developed countries. With the development of Gas Transmitting From West to East Project and natural gas industry, large numbers of gas storage will be built in China, so it is important to analyze the stability of salt cavern. The stability and creep of salt caverns #1 and #2 in Jintan Salt Mine are simulated by the famous finite difference software FLAC3D; and the results show that volume reduce ratio of salt caverns is within 22 percent as running pressure of gas storage between 6 MPa and 14.5 MPa, which can give guidance to build and management of gas storage. |
