摘要:

地热是一种清洁的可再生能源,开发利用北京市地热能可以为改善北京地区的大气环境发挥重要作用。对北京昌平新城区进行地热资源量评价,为合理开发利用地热资源提供科学依据。在分析昌平新城区内的地质条件、地热地质条件后,创建了昌平新城三维地质模型,以此计算热储体积;运用热储法获得区内地热储量,并分析地热资源的分布。采用三维地质建模方法,实现了研究区地质结构的可视化和地热储量的准确计算。研究区的热储总体积为4.876×1011 m3,地热储量为5.42×1016 kJ,地热流体可开采量为6.04×106 m3。研究区的地热资源潜力较大,可为当地绿色发展提供支撑。

Abstract:

As a clean renewable energy, geothermal energy has played an important role in improving the atmospheric quality of Beijing. This study evaluates the geothermal resource in the Changping New Town, Beijing, and provides scientific basis for rational utilization of geothermal resource in this area. After analyzing the geological and geothermal conditions in the study area, we built a 3D geological model of the Changping New Town, which is used to calculate the volume of reservoirs,then the geothermal reserve is calculated with the volumetric method, and the geothermal resource distribution is analyzed. 3D geological modeling is used to visualize the local geological structures and calculate the geothermal reserve. The estimated reservoir volume in the study area is 4.88×1011 m3 and the geothermal reserve is 5.42×1016 kJ. The exploitable volume of geothermal fluid is 6.04×106 m3. The geothermal resource in the study area is likely of great potential, and can support locally green development.

Key words: Changping, 3D geological modeling, geothermal resource, volumetric method
