福建漳州干热岩资源选址与开发前景分析

 由于干热岩具有传统化石能源不可比拟的优势,越来越多的国家将干热岩的勘探开发列入了国家能源发展计划。中国干热岩相关研究尚处于起步阶段。在分析研究目前各国干热岩开发利用工程的基础上,阐述了干热岩开发的地热地质学指标,针对福建漳州的干热岩科学钻探,从区内酸性岩体分布、盖层情况、深部热异常及区域稳定性等方面分析了福建漳州干热岩钻探选址的原则与指标,建立了钻孔位置地区的概念模型,并对福建漳州干热岩资源的开发前景做出分析。

Site selection and development prospect of a hot dry rock resource project in Zhangzhou geothermal field,Fujian province

Hot dry rock (HDR) geothermal resources have been listed in the national energy development plan by increasing countries owing to their incomparable advantages over conventional fossil fuels. HDR research is still at the early stage in China. Based on analyses of exploitation projects of HDR in the world, we propose several geothermal and geological indexes for HDR development. We take the HDR resource project in Zhangzhou geothermal field as an example to discuss the rules and indexes for site selection through analyses of acidic rock distribution, cap rock condition, deep geothermal anomaly, and regional stability. We also build a conceptual model of the drilling area of Zhangzhou geothermal field, estimate the deep geothermal reservoir temperature, and put forward suggestions for future development of HDR geothermal resources in Zhangzhou.
