摘要
AMT法是通过观测天然交变电磁场在大地中激励的电磁场的频率特性来研究地电参数(视电阻率)沿深度的变化。AMT可以提供TE/TM两个模式的电阻率用于反演,通过电阻率差异判断构造信息。本文介绍了AMT法在勘查地下热水方面的应用,结果表明,AMT法可以有效地探测出断裂构造及其导水通道,为找寻中深部地热水提供可靠依据。
The AMT method studies the variation of geo-electric parameters( apparent resistivity) along the depth by observing the frequency characteristics of the electromagnetic field excited by natural alternating electromagnetic field in the earth. AMT can provide the resistivity of TE/TM two modes for inversion, and judge the structural information by the difference of resistivityThis paper introduces the application of AMT method in the exploration of underground hot water. The results show that the AMT method can effectively detect the fault structure and its water channel, and provide a reliable basis for the search of middle and deep geothermal water.
