摘　　要：以电法资料为主,在测井的岩性、电阻率等物性资料基础上,综合重、磁、电、震各方法的反演结果,分析各种物探方法反演结果的相容性与相背性,重新修改模型建立统一的地质模型,对电法资料进行反演成像,确定深层的地质属性。Using several kinds of geophysical exploration methods to construct inversion model for electric inversion imaging interpretation to predict lithology can solve multi-solution property. Based on electric data, and property of lithology and resistivity of logs, and combining gravity, magnetic, electric and seismic inversion results, this paper analyzes the compatibility and incompatibility of the inversion result of different geophysical exploration methods, reviews the model to construct a unified geologic model, finishes inversion imaging of electric data, and finally determines the deep geologic attribute. The inversion result of Songshen I line and Songshen III line proves that the lithology change of Jurassic can be determined according to its electric change rules, and the correlation of formations between rifts of Jurassic can be determined. This method can be used in studying volcanic rocks and glutenite reservoirs.
