中国东部岩盐层与其它岩石频繁互层.从建造储气盐穴是否有利出发,根据含盐段岩盐层夹层的不同将剖面结构类型分为三类:第1类夹层以可溶性盐类——钙芒硝及泥岩为主,该类较易建造盐穴;第2类型夹层以碎屑岩(泥岩、粉砂岩)为主,含少量易溶盐类,该类建造盐穴条件一般;第3类型夹层以石膏、硬石膏为主,含泥、砂岩,该类难以建造盐穴.在中国东部诸多盐矿区中,江苏金坛建造盐穴条件较好,易于建造盐穴.而江苏淮安、湖南衡阳、湖北潜江、河南舞阳等盆地条件较差,但在这些矿区中,选择盐层厚度相对较大,夹层较薄、水不溶物质含量较低的地段,亦可建造储气盐穴.

The halite bed of eastern China is frequentlyinterbedded with the other rocks. According to the different rock salt bed interlayer of salt bearing zone, the section structure is separated into three types including the first interlayer which is easy to build salt cavern and dominated by dissolubility salinastone-glauberite and mudstone, the second interlayer which is common to build it and dominated by clastic rock(mudstone, siltstone) with a little readily soluble salt as well as the third interlayer which is hard to build it and dominated by gypsum and anhydrite with mud and sandstone. It is easy to build salt cavern at Jintan area of Jiangsu province but hard to build it at some basins such as Wuyang city of Henan province. Some sections with thick salt bed., thin interlayer and fewwater insoluble substance are also good for build salt cavern.
