| 摘 要： | 内蒙古呼包盆地内蕴藏着较丰富的地热资源,但多开发于盆地的北部。为探明盆地南部地热地质条件,采用CSAMT与二维地震相结合的方法开展了地热资源的勘查。通过对获取数据的反演,充分利用不同物探方法的技术特点,对比分析了电性结构与地震断面处的地层、断裂和水文地质信息,结合地质资料进行了综合成果解释。初步探明了勘查区深部断裂的分布、地质结构等地热地质条件,为该盆地总体地热资源的综合评价与远景预测提供了地球物理勘测与地质调查依据。

| Abstract: | Abundant geothermal resources are stored in the Huhhot-Baotou Basin of Inner Mongolia Autonomous Region,which are mainly developed in the northern part of the basin.In order to find out the geothermal geological conditions in the southern part of the basin,the CSAMT method combined with 2D seismic method were used to conduct the geothermal resource exploration.Based on the measured data inversion,in combination with geological data and the full use of technical characteristics of different geophysical prospecting methods as well as the analysis and comparison of information concerning electrical property,stratum,fracture and hydrogeology of electrical structure and seismic site,the integrated interpretation is achieved with comprehensive research results.The distribution,geological structure and other geothermal geological conditions of the deep-seat faults in the exploration area were preliminarily ascertained.The study results provide the basis in geophysical prospecting and geological survey for comprehensive assessment and prospect forecast of geothermal resources in the basin. |
