摘要
为加快省内地热资源勘查评价工作,提高勘查效率、降低开发风险,特别是在隐伏储热构造区必须开展水文地质调查和地球物理勘探。主要运用音频大地电磁法(AMT),对贵州石阡县城西部地区的隐伏储热构造进行探测,通过分析实测AMT剖面电性结构,结合区域地质构造和热储地层的分布关系、岩石物性基础和隐伏储热构造特征,确定了研究区隐伏储热构造的空间展布特征以及储热盖层的分布,为划定地热靶区提供参考依据。
In order to speed up the geothermal exploration,improve the exploration efficiency and lower the risk of development,it's urgent to carry out hydro-geological survey and geophysical exploration,especially in the concealed reservoir area.This paper mainly uses the audio magnetotelluric(AMT)to detect the concealed thermal storage area in the western region of Shiqian county,Guizhou province.On the basis of the relationship between regional tectonics and the thermal reservoir,the physical properties of rocks and concealed thermal reservoir structure,the spatial distribution characteristics of concealed thermal reservoir structure and thermal reservoir caprock in the study area can be identified by analyzing the measured electrical structure of AMT profiles,and thus provide a reference basis for the delineation of geothermal targets.
