| 地下热水能够导致热储层位电阻率明显降低，且温度与电阻率低值区具有良好的一致性，因此低阻异常带是查明与地下热水有关的断裂构造、探测侵入岩体分布、圈定地下深部热储位置的重要标志。本文采用大地电磁测深法在太行山前徐水地区开展了地热资源探测，圈定了低阻异常带的展布范围，并据此总结了徐水断裂深部电性特征，结合低阻异常带空间展布特征对深部地热地质条件和赋存环境进行了分析。通过与邻近已知地热田对比发现，徐水断裂深部具有相似的储热条件，根据大地电磁测量成果圈定了地热异常区及地热成藏有利范围，为开展地热资源勘查提供了借鉴资料。 |

| Geothermal water can cause obvious decrease of resistivity of thermal reservoir, and its temperature is consistent with the low resistivity area Therefore,the low resistivity anomaly zone often becomes an important sign to identify the fault structure related to geothermal water,detect the distribution of intrusive rock mass,and delineate the location of deep underground thermal reservoir By using magnetotelluric sounding method,this paper has explored the geothermal resources of Xushui area in front of Taihang Mountain and delineated the distribution range of low resistivity anomaly zone Based on this,this paper has summarized the deep electrical characteristics of Xushui fault, and combined with the spatial distribution characteristics of low resistivity anomaly zone,has analyzed the deep geothermal geological conditions and occurrence environment Compared with the adjacent known geothermal elds,it has been found that the deep part of Xushui fault has the same heat storage conditions According to the results of magnetotelluric survey,the geothermal anomaly area and the favorable range of geothermal accumulation have been delineated,which provides reference data for geothermal resources exploration in this area |
