摘　　要：地下介质电阻率能够综合反映多孔介质及其所含流体的电学信息,在多孔介质均匀的情况下,能够反映地下介质含水量的空间分布。本研究以承德南部地区层状热储为例,利用可控源音频大地电磁方法获得了剖面电阻率,建立了电阻率分布与地下介质构造及含水量的对应关系。研究表明,在岩性均一的条件下,地球物理勘探是研究层状热储的有效手段。The electrical resistance could comprehensively reflect the electrical property of the fluid in layers.While,the distribution of the fluid in layers could be depicted by the electrical resistance with the similarity of the lithology and porosity.In this study,a method for investigation the structure of layered thermal reservoir has been discoursed based on an CSAMT profile with a similarity lithology.
