我国地热资源哪里多？一张图看分布，年可采量超26亿吨煤
摘要：
中国地热资源禀赋良好,分布广泛且具有明显的规律性和地带性。本文系统总结了国内取得的地热资源勘查开发成果:浅层地热能资源在全国范围内普遍分布,我国336个地级以上城市规划区范围内浅层地热能资源年可开采量折合标准煤7亿吨;水热型地热资源年可开采量折合标准煤19亿吨;干热岩远景资源量折合标准煤856万亿吨。阐明了有代表性的水热型地热资源成因机制和干热岩资源成藏模式。地热开发利用技术发展迅速,浅层地热能和水热型地热资源利用量逐年攀升,但在地热资源成藏模式研究、勘查开发及管理利用等方面仍有亟须突破的技术瓶颈和需要改进的环节。文章分析了存在问题并提出了我国地热发展战略路线,下一步应加强热源机理与控热构造研究,推进地热探测技术和开发利用示范,开展重点地区浅层地热能、水热型地热资源勘查评价,完善干热岩勘查开发技术体系,推动地热产业健康有序发展。

Abstract:
China is well endowed with geothermal resources that is widely distributed with distinctive distribution pattern and regional characteristic. In this work, we systematically summarized the recent nationwide achievements in geothermal energy developments. Shallow geothermal resources are extensively available throughout the country. For 336 above prefecture-level cities, the annual recoverable amounts of shallow geothermal and hydrothermal resources were equivalent to 700 million and 1.9 billions tons of standard coal, respectively; the prospective amount of hot dry rock resources was equivalent to 856 trillion tons of standard coal. We also discussed the typical genetic mechanism of hydrothermal and hot dry rock resources. Rapid progresses of geothermal energy development and utilization technology have seen increasing shallow geothermal and hydrothermal resources explorations year by year. However, technical bottlenecks and imperfections still need to be resolved urgently in the areas of geothermal resource genesis, exploration and utilization management. In order to promote an healthy and orderly development of geothermal industry, future improvements should be focus on enhancing studies of resource genesis and geothermal tectonics and exploration technology, advancing geothermal technology and development and utilization demonstrations, assessing shallow geothermal and hydrothermal resources in key areas, and perfecting developmental and exploration methodologies for dry hot rock geothermal resource.
