摘　　要：开发与利用盐矿已形成的采卤老溶腔是快捷建成储气库的有效方式(除加快新腔的形成速度外)。利用老溶腔不但可以缩短建库时间,还可以减少盐穴储气库的建设成本。为此,在考虑储气库要求及老溶腔特点的基础上,提出了已有采卤老溶腔改建储气库的地质条件和腔体条件,论述了评价已有采卤老溶腔所需要的工程施工项目,建立了一整套采卤老腔改建储气库的评价方法与分析技术,包括声纳检测数据分析技术、腔体力学稳定性评价方法、社会和经济效益评价内容等,并结合金坛盐矿的实例进行了论证。目前该方法已成功应用在西气东输盐穴储气库的老腔改造工程中。To build gas storage on the basis of development and utilization of the formed old salt cavern in salt mine is a kind of fast and effective technique (except for accelerating the construction of the new cavern). The construction based on old salt cavern can not only shorten the construction cycle, but also reduce the construction cost. Based on the consideration of gas storage requirement and characteristic of old salt cavern, the geological conditions and cavern conditions of existent gas storages which were built on old salt cavern were brought forward. The existing old salt cavern construction projects were discussed. A full set of appraisal methods and analysis technologies for the construction of old salt cavern gas storage were established, including sonar inspection and statistics analysis technique, cavern mechanical stability appraisal technique, appraisal method on social and economic performance, etc. Meanwhile, Jintan salt mine was taken as an example to conduct a series of discussions and evaluations. Up to now, the method has been applied in the 'West-to-East Natural Gas Transmission Project' for the salt cavern reconstruction.
