摘　　要：山东省岩盐矿产分布于大汶口盆地、东营盆地、东明盆地及单县黄岗盆地中。在参考前人研究成果基础上,根据建造储气盐穴库的必要条件和地质评价方法,对山东省各岩盐矿区建造储气盐穴库适宜性进行地质分析评价。东营盆地和东明盆地岩盐矿层顶板埋深在2000~3000m以下,不适合建造储气盐穴库;大汶口盆地采盐老腔由于不稳定,难以改造成储气盐穴。该矿区由于岩盐矿层厚度小,夹层厚度大,且多为较坚硬岩石,亦不宜建造储气盐穴;黄岗盆地盐层较厚,建造储气盐穴地质条件较好,但可溶盐含量较低,建造的盐穴有效体积偏低。但该盆地勘查程度低,有望找到矿层更好、更适合建造储气盐穴库的地段。Rock salt minerals in Shandong province are distributed in Dawenkou basin,Dongying basin,Dongming basin,and Huanggang basin of Shan county.Based on the previous research results,according to the necessary conditions and geological evaluation methods of building salt caves for gas storage.the geological analysis and evaluation of the suitability for building gas caves for gas storage in Shandong province are carried out.The buried roof depth of rock salt mine layer in Dongying basin and Dongming basin is below 2000~3000m,which is not suitable for building salt cave for gas storage.The old salt mining cavities in Dawenkoubasin,because of it’s instability,is difficult to transform into salt cave for gas storage.Due to the small mineral thickness,large interlayer thickness,and mostly hard rock,these old salt mining cavities are not suitable to build salt cave for gas storage.In Huanggangbasin,the salt layer is thick with good geological conditions,but the soluble salt content is low,the salt hole built has a low effective volume.However,the exploration degree of this basin is low,and it is expected to find a better and more suitable area for the construction of salt cave for gas storage.
