开封凹陷区深层地热资源评价

为推动清洁能源的开发利用，减少碳排放，服务国家清洁取暖试点城市建设，以开封市区为例，评价分析了开封凹陷区深层地热资源。根据研究区内存在的开封断裂和祥符—刘店断裂，把研究区切割为4个区块进行研究，计算得出，新生界热储储存热水资源总量为107.47×10 10 m 3；地热储存热量为439.90×10 18 J。根据《地热资源地质勘查规范》（GB 11615—2010）对地热田规模的划分，得出3个大型地热田，分别为新近系明化镇组热储、新近系馆陶组热储和古近系热储。研究确保地热能安全可持续开发利用，推进清洁能源开发利用进程；可为后期城市发展规划和建设项目布井方案（采灌井比、采灌井间距）提供地热能源利用技术依据。

Evaluation of deep geothermal resources in Kaifeng Sag

In order to promote the development and utilization of clean energy，reduce carbon emissions，and serve the construction of national clean heating pilot cities，this paper took Kaifeng urban area as an example to evaluate and analyzed the deep geothermal resources in the Kaifeng depression.According to the Kaifeng fault and Xiangfu-Liudian fault existing in the research area，the research area was divided into 4 blocks for research，and it was calculated that the total amount of thermal storage and hot water resources in the Cenozoic is 107.47×10 10 m 3；geothermal storage heat is 439.90×10 18 J.According to the division of geothermal field scale in "Geological Exploration Specification for Geothermal Resources" （GB 11615—2010），three large-scale geothermal fields were obtained，which are Neogene Minghuazhen Formation thermal storage，Neogene Guantao Formation thermal storage and Paleogene thermal storage.This research can ensure the safe and sustainable development and utilization of geothermal energy，and promote the development and utilization of clean energy；provide a technical basis for geothermal energy utilization for later urban development planning and construction projects （ratio of extraction and irrigation wells，spacing between extraction and irrigation wells）.
