可控源音频大地电磁测深在深部地热资源勘查中的应用

AN APPLICATION OF CSAMT SOUNDING TO EXPLORATION OF DEEP GEOTHERMAL RESOURCES

电法一直是寻找地热资源的主要手段,随着地热资源开采深度加大,常规电法已经难以满足实际工作需要,近几年来,我所采用可控源音频大地电磁测深法在地热资源勘查工作中完成大量工作,并取得了令人十分满意的应用效果。这里主要介绍一些具有代表性的地热资源勘查实例和应用成果。

Electrical methods used to be the main tools for exploration of geothermal resources. However, conventional electrical methods have no longer met requirements of practical surveys for geothermal resources as detection depth required becoming deeper and deeper nowadays. In recent years, a large quantity of geothermal surveys has been completed by IGGE with CSAMT sounding, with quite satisfied results obtained. Introduced in the paper are some case histories.
