    宁夏银川市浅层地温能赋存条件和开发利用潜力评价

    Conditions for the Occurrence and Development and Utilization Potential Evaluation of Shallow Geothermal Energy in Yinchuan City, Ningxia

    • 摘要: 扩大浅层地温能这种可再生绿色能源的开发利用规模,对中国的节能减排和可持续发展具有重要的意义。本次通过银川市浅层地温能资源调查,查明了宁夏银川市浅层地温能蕴藏条件。本研究利用Arcgis软件使用层次分析法对研究区进行地埋管地源热泵适宜性分区,并进行浅层地温能资源潜力评价。研究认为,研究区范围无地埋管地源热泵不适宜区,适宜区面积分布最广为1767 km2,占比为56.04 %;较适宜区面积为1386 km2,占比为43.96 %;研究区地埋管地源热泵开采潜力较大,夏季开发潜力为42.7万 m2/km2,冬季开发潜力为36.0万 m2/km2。根据研究成果提出研究区浅层地温能资源开采和规划意见,为后续制定开发利用方案提供思路与依据。

       

      Abstract: Expanding the scale of development and utilization of shallow geothermal energy is of great significance for energy conservation, emission reduction and sustainable development in China. The investigation and evaluation of shallow geothermal energy in Yinchuan started late. In order to avoid blind exploitation of shallow geothermal energy, the occurrence conditions of shallow geothermal energy and the evaluation of development and utilization potential are important technical support. By identifying the occurrence conditions of shallow geothermal energy in Yinchuan, the suitability zoning of ground source heat pump with buried pipe in the study area was carried out by using analytic hierarchy process (AHP) and Arcgis software. Finally, the potential of shallow geothermal energy resources was evaluated. The results show that there is no unsuitable area for ground source heat pump with buried pipe in the study area, the most suitable area which is most widely distributed is 1767 km2, accounting for 56.04 %. The comparatively area is 1386 km2, accounting for 43.96 %. The development potential of ground source heat pump with buried pipes in the study area is huge, the development potential in summer is 42.7 million m2/km2, and the development potential in winter is 36.0 million m2/km2. Based on the research results, the development and utilization giving suggestions of shallow geothermal energy in the study area were given to provide ideas and basis for the subsequent development and utilization plan.
