音频大地电磁测量法（AMT）在莒县地区地热勘查中的应用

Application of Audio Magnetotelluric Method (AMT) in Geothermal Exploration in Juxian County

摘要:

利用音频大地电磁测量（AMT）法在莒县东部沭东新区进行地热资源勘查，通过前期实地踏勘和对采集的数据经过各项处理后进行反演,结合地热资源赋存有关的水文地质条件,对反演图件进行推断解释,查明了区内主要断裂构造位置、产状、规模及地下热储层深度，取得了较好的应用效果。

Abstract:

Audio magnetotelluric (AMT) method has been applied in exploring geothermal resources in Shudong new district in eastern Juxian county. Through field survey and data collection on the processing after inversion, combining with hydrogeological conditions of geothermal resources occurrence, the interpretation of inversion maps in this region has been carried out. Fault location, occurrence, the size and the depth of underground heat reservoir have been identified, and achieved a good application effect.
