摘　　要：地热作为可再生清洁能源,在实施燃煤替代、优化能源结构、促进低碳绿色发展中,受到愈来愈多的重视。通许凸起东部(睢县-商丘段)地热田为通许凸起内新增的新生界和古生界复合型中低温地热田,其热储层主要有新近系孔隙热储、古近系裂隙孔隙热储和古生界寒武-奥陶系碳酸盐岩溶蚀裂隙热储,其中古生界寒武-奥陶系碳酸盐岩溶蚀裂隙热储为商丘地区新发现并首次探获成功的具有开发价值的热储层。根据项目实施所得数据及地质资料综合分析进行地热资源评价,通过建立热储模型,估算地热田2000 m以浅的地热流体资源储存量为8075.83×1016J,地热流体可开采量1279.26×1012 J/a,折合标准煤60927.31t/a,达到中型地热田规模,为制定该区地热能勘查、开发利用规划,地区地热规模化开发提供了有利的技术支持。Geothermal as a renewable clean energy, has been paid more and more attention in the implementation of coal replacement, optimization of energy structure and promotion of low-carbon green development. The geothermal field in the east of Tongxu uplift(Suixian Shangqiu section) is a new composite type of middle and low temperature geothermal field of Cenozoic and Paleozoic in Tongxu uplift. Its thermal reservoir mainly includes Neogene pore thermal reservoir, Paleogene fracture pore thermal reservoir and Paleozoic Cambrian Ordovician carbonate dissolution fracture thermal reservoir, among which the Paleozoic Cambrian Ordovician carbonate dissolution fracture thermal reservoir is a new development in Shangqiu area. Now and for the first time, a successful thermal reservoir with development value has been found. According to the comprehensive analysis of the data and geological data obtained from the implementation of the project, the geothermal resource evaluation is carried out. Through the establishment of the thermal storage model, the shallow geothermal fluid resource storage capacity and exploitable geothermal fluid capacity within 2000 m of the geothermal field are estimated, reaching the scale of medium-sized geothermal field, which provides favorable technical support for the formulation of the geothermal energy exploration, development and utilization plan and the regional geothermal large-scale development.
