可控源音频大地电磁法在西南地热资源勘查中的应用

Application of controlled-source audio-magnetotelluric technique in the geothermal resource exploration in Southwest China

采用可控源音频大地电磁法对西南某地的地热资源进行了勘查,结合地质、地球物理特征,对数据资料进行了处理与反演解释。基本查明了深部热源花岗岩的埋深、导热通道断裂的性质等。地球物理勘查成果为勘查区地热资源钻井的井位、设计井深提供了基础资料。

After survey in way of controlled-source audio-magnetotelluric technique （CSAMT） for geothermal resources in a certain part of southwest China, in addition to summarization of geological and geophysical characteristics as well as the processing, inversion and interpretation of data, the depth of deep heat source granite and the characteristics of thermal conductive pathway fracture are basically found out. These geo- physical exploration results provide basic data for locations and designed depth of geothermal resource drill- ing in the exploration area.
