黄河流域(济阳段)地热资源在乡村振兴中的应用研究

    Research on the application of geothermal resources in rural revitalization in the Yellow River Basin (Jiyang Section)

    • 摘要: 黄河流域生态保护和高质量发展是国家重大战略。为了助力乡村振兴,促进当地地热资源可持续开发利用,依托黄河流域(济阳段)地热资源调查项目,查明了研究区地热地质条件、热储特征、地热流体特征;在非回灌条件下采用降压试验的方法估算了DS-1井在降深50 m时,可开采量为819.66 m3/d,采用热储法估算地热资源量为1.14×1019 J。研究区地热资源储量丰富,但开发利用程度较低,已利用地热井主要用于供暖、养殖、洗浴等,利用方式单一。针对研究区内地热资源应用问题,提出了合理化建议:结合济阳区乡村振兴发展规划,在济阳垛石慢城综合体建设中,DS-1井可直接用于“地热+供暖”;研究区内地热水富含多种矿物质,可利用于“地热+温泉康养”;将研究区内地热资源与其他清洁能源有机整合,打造“地热+”绿色发展模式,因地制宜建设“地热+综合能源体系”。研究区内地热资源丰富、医疗价值高、开发利用前景广阔,可以从地热供暖、康养洗浴、农业养殖、温泉旅游、生态保护等多方面精准服务于垛石街道“生态+”的乡村振兴模式。

       

      Abstract: Ecological conservation and high-quality development of the Yellow River Basin is a major national strategy. In order to assist in rural revitalization and promote the sustainable development and utilization of geothermal resources in the local area, based on the Yellow River Basin (Jiyang Section) geothermal resources survey item, the geothermal geological conditions, heat storage characteristics and geothermal fluid characteristics in the research area have been identified. By using the depressurization test in non-recirculation method, estimates that when the depth of the well DS-1 is reduced by 50 m, the exploitable reserve is 819.66 m3/d, by using the thermal storage method, estimates the geothermal reserve is 1.14×1019 J. The research area has abundant geothermal resources reserves, but the degree of development and utilization is low. The utilized geothermal wells are mainly used for heating, breeding, bathing, etc., and the utilization mode is single. Aiming at the application problems of geothermal resources in the research area, puts forward reasonable suggestions. In combination with the rural revitalization and development plan of Jiyang City, the well DS-1 can be directly used for “Geothermal + Heating” in Jiyang Duoshi slow city complex construction; the geothermal water in the research area is rich in various minerals, which can be used for “Geothermal + Hot Spring Wellness”; integrating geothermal resources in the research area with other clean energy sources, creating a “Geothermal+” green development model, the “Geothermal + Comprehensive Energy System” can be developed according to local conditions. The research area has abundant geothermal resources, high medical value, and broad prospects for development and utilization. It can accurately serve the “ecological+” rural revitalization model of Duoshi Street from various aspects such as geothermal heating, health and bathing, agricultural breeding, hot spring tourism, and ecological protection.
