CSAMT法在浙江东阳水口一带地热勘查中的应用

Application of CSAMT Method in Geothermal Exploration in Shuikou Area, Dongyang City, Zhejiang Province

为满足水口一带开发建设对地热资源的需求,本研究采用可控源音频大地电磁法(CSAMT)在工作区开展了地球物理勘查工作。本次地球物理勘查基本查明工作区内地质构造的空间展布情况,解译了3条断裂带,分析了3条断裂带之间的切割关系、走向、倾向、含水性等,从而圈定两个水富集区。钻孔成果验证该方法对于地热勘查的有效性。

In order to meet the needs of geothermal resources for the development and construction of Shuikou area, the CSAMT method was used to carry out geophysical exploration in the work area in this study. The geophysical exploration basically ascertained the spatial distribution of geological structures in the work area, interpreted three fault zones, analyzed the cutting relationship, strike, tendency and water content among the three fault zones, and delineated two water-enriched zones. The drilling results verify the validity of this method for geothermal exploration.
