摘要
采用可控源音频大地电磁法、米地温测量、阿尔法卡法(测氡)三种物探方法对贵州金沙县城北地热资源进行勘查,利用各方法数据、图件,结合地质条件和地球物理特征,对物探资料综合分析解释,初步查明测区地热分布特征,尤其是对深大断裂揭示及其导水导热性能判定更具实际意义,通过钻孔验证,最终证实综合物探方法在厚覆盖层地区地热资源勘探中的可行性。
The terrestrial heat resources in N part of Jinsha, Guizhou are exploraed with controllable audio frequency magnetotelluric method, M low T measurement, Alpha Card method 3 geophysical exploration methods, utilization data, diagram of each method, in combination with geological condition and geophysical characteristics, comprehensive analysis and interpret th geophysicl exploration material, preliminarily find out the terrestrial heat distribution characteristics of the area, especially showing the megafaultand their diversion, heat conduction capacity, according to the drill hole examination, finally confirm the feasibility of comprehensive geophysical exploration method in terrestrial heat resources exploration of thick covering area.
