摘　　要：近年来通过多地岩盐矿区试验,已证明岩盐水溶开采形成的地下溶腔是储备石油、天然气的理想场所。淮安地区开展岩盐钻井水溶开采多年,已形成大量地下溶腔资源。对水溶开采岩盐的溶腔形态及其发展变化的影响因素进行研究,已具有十分重要的意义。文章对选取的淮安地区岩盐钻井的溶腔形态现状进行了研究,发现溶腔在不同盐盆矿床中呈不同形态:在淮安盐盆呈上部倒喇叭状,下部圆柱状的形态,在洪泽盐盆呈上窄下宽糖葫芦状的形态。文章通过分析认为岩盐的溶解规律和岩盐矿层的特征为地下溶腔形态发展变化的主要影响因素。The results of the many experiment recently show that the reasonable storage space of the oil and natural gas is the dissolved salt cavity with solution mining.There are such a lot of salt cavities with solution mining in Huai’an.So it is of great importance of the studying on structural configurations and influence factors of the dissolved salt cavity with solution mining.It is discovered that there are different many structural configurations in different salt basins,by studying many forms of the salt mines selected in Huai’an,sush as the inverted-horn upward and cylindroid downward cavities in Huai’an salt basin,and the dissolved salt cavitie is wide at the top and narrow at the bottom in Hongze salt basin.The main influences of the shape changes with the underground cavity are the salt dissolution behavior and the characters about the salt layer.
