| 中文摘要: |
| 地热资源是一种储量大、分布广的清洁绿色、低碳可再生能源，大力推进地热能开发对我国实现“双碳”目标、推动绿色能源结构调整具有重要意义。京津冀地区地热资源储量丰富，研究地热资源热储赋存特征、准确评估地热资源量是实现地热资源可持续开发利用、推进“双碳”目标的重要途径之一。从地质构造来看，天津市新近系馆陶组分布范围横跨多个构造单元，热储属新近系河流相碎屑岩沉积，分布面积为8 435.2 km2。本研究以天津市新近系馆陶组热储为研究对象，对热储空间分布及热储特征进行了分析，综合运用热储法、采灌均衡法开展深入研究。结果表明，通过热储法计算馆陶组地热资源量为154.04×1018 J，可折合标准煤52.56×108 t，地热流体储存量为359.39×109 m3。采用采灌均衡法在回灌条件下计算馆陶组地热流体可开采量为4.11×108 m3/a，地热流体可开采热量为679.36×1014 J/a。本文对新近系馆陶组地热资源开发利用潜力进行评价，为天津市及京津冀地区地热资源合理开发提供关键数据支撑。 |

| Geothermal resources are a type of clean, green, low-carbon renewable energy with large reserves and wide distribution. Vigorously promoting geothermal energy development is of great significance to China in achieving its "dual carbon" goals and advancing the adjustment of the green energy structure. The Beijing-Tianjin-Hebei region is rich in geothermal resources. Analyzing the occurrence characteristics of thermal reservoir resources and accurately assessing geothermal resource reserves are important approaches to realizing the sustainable exploitation and utilization of geothermal resources and promoting the "dual carbon" initiative. From a geological structure perspective, the Guantao Formation spans multiple tectonic units. Its thermal reservoir consists of fluvial clastic rock deposits and is absent in some areas, with a total distribution area of 8 435.2 km2 in Tianjin. Taking the Guantao Formation thermal reservoir in Tianjin as the primary research object, this study analyzes the spatial distribution and reservoir characteristics of the thermal reservoir and conducts in-depth investigations by comprehensively applying the thermal reservoir method and the injection-production balance method. The results show that the geothermal resource quantity of the Guantao Formation, calculated using the geothermal reservoir method, is 154.04×1018 J, equivalent to 52.56×108 t of standard coal, with a geothermal fluid storage capacity of 359.39×109 m3. For the injection-production balance method, the allowable annual exploitation volume of geothermal fluid, calculated based on the single-well exploitation right protection radius under reinjection conditions, is 4.112×108 m3/a, and the allowable annual exploitable heat energy is 679.37×1014 J/a. In addition, a comprehensive evaluation and zoning of the development and utilization potential of Guantao Formation geothermal resources are carried out, which provides key data support for the rational exploitation of geothermal resources in Tianjin and the Beijing-Tianjin-Hebei region. |
