综合物探在冀东北部山区地热资源勘查中的应用

冀东北部山区地热资源丰富，利用综合物探方法对查找深大断裂构造，圈定地热异常范围有着良好的效果。本文以冀东北部山区某项地热勘查项目为研究对象，在研究区实施了以可控源音频大地电磁技术（CSAMT）与视电阻率测深为主的勘查手段，两种技术方法的应用大致揭露了本研究区构造走向及位置，查明2条主要控热导热构造F01、F02。辅以激电测深技术，加之6参数对含水层与断裂的良好反应，基本确定了热储位置及空间分布规律。圈定了地热异常区与地热资源可开发利用的范围，为下一步地热地质勘查与钻探布孔工作提供了科学依据。

Application of comprehensive geophysical exploration in geothermal resources exploration in northern mountainous area of eastern Hebei Province

In this paper， a geothermal exploration project in the northeastern mountainous area of Hebei Province is taken as the research object. In the study area， controlled source audio magnetotellurism （CSAMT） and apparent resistivity sounding are adopted as the main exploration means. The application of the two technical methods reveals the strike and location of the structure in the study area， and two main heat-controlling and heat-conducting structures F01 and F02 are identified. With the help of IP sounding technology and the good response of six parameters to aquifer and fault， the location and spatial distribution of heat reservoir are basically determined. The delineation of geothermal anomaly areas and the scope of geothermal resources for exploitation and utilization provides a scientific basis for the next geothermal geological exploration and drilling.
