| 摘 要： | 地热资源调查是皖江经济带地质调查的重要工作之一,是调整能源结构,构建环境友好型社会的要求。基于皖江经济带以往地热资源调查评价成果,阐述研究区地热资源的分布特点、形成机理、种类及资源总量,分析总结研究区目前地热资源开发利用现状及存在问题: 皖江经济带地热资源虽然丰富,但仅有部分水热型地热资源开发利用程度高,且资源利用效率较低; 水热型地热资源以温热水、温水为主,总体品位不高; 浅层地热能资源总量丰富,分布广泛,开发利用技术成熟,适宜大力开发利用,但大部分未开展调查评价工作。建议采取梯级或循环利用措施提高利用效率,综合开发利用地热资源; 突破现有模式,寻找高品位地热资源; 开展县级浅层地热能调查评价工作; 建设地热资源开发利用监管平台。

| Abstract: | Based on previous survey and evaluation achievements of geothermal resources in Wanjiang Economic Belt, the authors expounded on the distribution characteristics, formation mechanism, categorie and resources quantity of geothermal resources in this area, analyzed the current situation of exploitation and utilization, and the following issues. Although the geothermal resources in Wanjiang Economic Belt are abundant, only part of the hydrothermal geothermal resources are highly developed, but with low utilization efficiency. The hydrothermal geothermal resources are mainly warm-hot and warm water with low grade. The shallow geothermal energy in the study area is abundant and widely distributed with mature technology of exploitation and utilization, so it is favorable for vigorous exploitation and utilization. However, most parts of the region lack survey and evaluation of shallow geothermal energy. Thus, the authors suggest that cascade or cyclic utilization measures should be adopted to improve efficiency, and the geothermal resources should be comprehensively utilized. The current prospecting model should be updated to search high-grade geothermal resources. The survey and evaluation of shallow geothermal energy should be made in the county level, and the monitoring platform of geothermal resources exploitation and utilization should be established. |
