摘　　要：我国的盐矿多为湖相沉积,含有不溶或难溶夹层,对盐穴油气储库建设具有重要影响。通过压制含夹层型盐试件、搭建水溶造腔试验平台、自制腔体测量装置,在室内进行了单夹层和双夹层的大尺寸型盐水溶造腔试验。结果表明,腔体测量装置能够准确测量油垫位置及腔体形状。夹层的存在会影响排卤口卤水的浓度,削减腔体容量。造腔步进行到夹层附近时,排卤口卤水浓度降低,造腔速度变缓。造腔完成后,整个溶腔被夹层分隔成若干个小型腔体,腔体容量缩小。Salt deposits in China are mostly lacustrine deposits with insoluble or insoluble intercalations,which have an important impact on the construction of salt cavern reservoir.For layered salt rock stratum,an indoor experiment of solution mining with single layer and double layers specimens has been studied by pressing layered specimens,building text platform and self-made cavity measuring instrument.The results show that:the position of blanket and shape of cavity can be measured accurately by cavity measuring instrument.The average concentration of brine in outlet is influenced by interlayer,when the phase of solution mining is around interlayer,the average concentration of brine in outlet will be decreased and the pace of solution mining will be slowed.After all the phases of solution mining have been finished,the cavity is formed by several small parts;the capacity of cavity is reduced by interlayers.
