摘　　要：我国盐穴地下储库建设起源于江苏金坛盐矿并获得成功,初步构建了我国盐穴储库建设首个技术标准体系。但是,我国各地盐矿的品位、埋深、矿层厚度和夹层特性等地质条件与金坛盐矿相差甚远,盐穴储库建设面临诸多挑战,不能照搬“金坛模式”。着眼于盐穴储库地质设计、造腔工程、注气排卤方案等方面,首先总结盐穴储库建库的“欧美模式”,以及基本上借鉴“欧美模式”发展形成的我国“金坛模式”的基本特征,然后结合我国已开展和正在开展的其他多座盐矿的盐穴储库建设的研究和工程实践,提出几种基于“一地一议、因矿制宜”原则的典型盐穴储库建库的“XX模式”。“XX模式”意味着是不同于金坛模式并有极大突破和变革的新型建库模式,是应对我国各地盐矿地质复杂性所带来挑战的技术方案和新思路。最后,对于下一步应对盐矿复杂地质条件带来的挑战需要突破和创新的关键理论和技术进行了展望。The construction of salt cavern underground storages in China originated from the Jintan salt mine in Jiangsu province,achieving success and establishing the first technical standard system for salt cavern storage construction in China.However,the geological conditions of other salt mines in China differ significantly from those of the Jintan salt mine,such as NaCl grade,buried depth,salt rock thickness,and interlayer characteristics.Therefore,the construction of salt cavern storage faces numerous challenges,and the“Jintan mode”cannot be directly replicated.Focusing on the geological design of salt cavern storage,solution mining engineering,and gas injection and brine discharge schemes,this paper firstly summarizes the“European and American mode”of salt cavern storage construction and the basic characteristics of China’s“Jintan mode”,which basically developed from the“European and American mode”.Then,based on research and engineering practices in salt cavern storage construction of other salt mines in China,several typical“XX modes”are put forward,adhering to the principle of“one solution design for one region or one salt mine”.The“XX modes”differ from the“Jintan mode”,with great breakthroughs and changes.They represent technical solutions and new ideas to deal with the geological complexities of salt mines in China.Finally,the key theories and technologies that need to be researched further in the next step to cope with geology challenges of salt mines are prospected.
