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

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.
