山东省砂岩热储地热资源开发利用模式探讨

通过对山东省砂岩热储地热资源、开发利用现状及存在问题的分析,结合社会、经济、环境效益及清洁能源应用需求,提出了地热供暖、梯级利用、多级取热、尾水回灌为适合山东省砂岩热储地热资源合理开发、高效利用及采灌均衡可持续开发利用模式。以此模式建立的山东省首个砂岩热储地热回灌示范工程——德州市水文家园,示范效果良好,促进了山东省鲁北地区地热供暖产业的持续健康发展,实现了社会、经济、生态环境的共赢。

Development and Utilization of Geothermal Resources in the Middle and Deep Layers of Shandong Province

Through analysis on geothermal resources, present condition of development and utilization and existing problems in the middle and deep layers of Shandong province, combining with social, economic, environmental benefits and application requirements of clean energy, geothermal heating, cascade utilization, multistage heating and tail water recharge are put forward as reasonable exploitation, high efficiency utilization and balanced and sustainable exploitation and utilization mode of sandstone thermal reservoir geothermal resources in Shandong province. The first sandstone thermal storage geothermal recharge demonstration project established in this model in Shandong province promoted the sustainable and healthy development of the geothermal heating industry in Lubei area in Shandong province, and achieved a winwin situation in society, economy and ecological environment.
