摘　　要：干热岩作为地热资源的重要组成部分,具有清洁、稳定、可再生的优势,潜力巨大。研究干热岩对于湖北省能源利用、环境保护意义重大。因此,对湖北省具有干热岩成藏条件的干热岩靶区进行分析,选择大别地区罗田和江汉盆地嘉鱼,采用大地电磁探测技术进行模型二维正演。最后通过野外数据采集,对TM模式数据进行反演解译,基本查明两地深部电性结构,推测控热构造的分布规律,初步评估其干热岩潜力。As an important component of geothermal resources,hot dry rock has the energy advantages of clean,stable and renewable,and has great potential.Research on HDR is of great significance to environmental protection,energy utilization in Hubei province.Therefore,in this paper,the target area of HDR with conditions for accumulation of HDR in Hubei province is analyzed,and Luotian in Dabie area and Jiayu in Jianghan Basin are selected.MT is used and 2D forward simulation is carried out.Finally,through field data collection and inversion interpretation of TM model data,the deep electrical structure of the two places is basically identified,the distribution law of thermal control structure is speculated,and the potential of dry hot rock is preliminarily evaluated.
