| 摘 要： | 介绍了应用可控源音频大地电磁测深法(CSAMT)解决地表覆盖层较厚地区深部地热勘査的问题。利用该方法抗干扰及高分辨率的优势,消除了覆盖层的影响,并在总结勘查区区域地层构造、地质构造、地热地质、地球物理条件等基础上,根据CSAMT反演电性结果推断出地层及断裂构造的分布情况。根据异常设计钻孔,钻探证实了该方法寻找深部地热的可行性。

| Abstract: | This paper introduces the application of controlled source audio frequency magnetotelluric method(CSAMT)to explore the deep geotherm existing in the surface of thick overburden covered area.Besides,it takes advantage of the anti-interference and high resolution to eliminate the influence of thick overburden layer.Based on the analysis of the regional stratigraphic structure,geological structure,geothermal geology,geophysics and other conditions in the exploration area,the distribution of stratum and faults is inferred by inversion results of the CSAMT.According to the abnormal resistivity,the borehole has been designed.What's more,the drilling results have proved that CSAMT method is feasible to prospect the deep geotherm. |
