| 中文摘要: |
| 开展矿产资源开发利用水平调查评估，有利于及时摸清矿产资源利用家底，是严守资源安全底线、推动绿色低碳发展的重要举措。本文聚焦天津市地热资源开发利用水平调查评估研究工作，分析地热能利用率、地热流体回灌率水平和开发利用水平评估现状，探讨其影响因素进而提出优化建议。研究结果表明：天津市孔隙型和岩溶裂隙型地热流体回灌率分别为94.06%和98.94%；天津市地热矿山开发利用水平较高，武清区、滨海新区处于领先；资源禀赋、政策管理与企业开发行为共同影响开发利用水平；孔隙型矿山地热流体回灌水平较高，而岩溶裂隙型矿山的地热能利用水平相对较高；部分企业因采用梯级利用、高效回灌等技术，处于领先水平。优化建议包括：针对开发利用水平落后的矿山，通过采用梯级利用技术、加大地热回灌井建设、采用大口径填砾成井、射孔成井和人工储层改造等方式提高开发利用水平；完善评估指标体系，将开发利用程度纳入开发利用水平评估指标，改进固定比例划档方法，建立非供暖型矿山指标体系。 |

| Conducting regular surveys and assessments of the level of mineral resources development and utilization helps to timely ascertain the actual status of resource utilization and constitutes a key measure for strictly safeguarding the bottom line of resource security and advancing green and low-carbon development. Focusing on the survey and evaluation of geothermal exploitation and utilization level in Tianjin, this paper examines the geothermal energy utilization rate and the geothermal fluid utilization rate, and the evaluation status of geothermal resource exploitation and utilization level, followed by an in-depth analysis of the influencing factors, and then puts forward optimization suggestions. The research results indicate that: In Tianjin, the average geothermal fluid utilization rate is 94.06 % for porous geothermal mines and 98.94 % for karst fissure geothermal mines, while the average geothermal energy utilization rate across all geothermal mines reaches 74.96 %. The average geothermal resources exploitation and utilization level of geothermal mines in Tianjin is 72.53 points, with Wuqing District and Binhai New Area maintaining a leading position. This level is jointly affected by resource endowment, policy management, and enterprise development practices: porous geothermal mines exhibit a relatively higher geothermal fluid recharge level, whereas karst fissure geothermal mines show a higher geothermal energy utilization level. In contrast, some enterprises have attained a leading position by adopting cascade utilization and efficient geothermal fluid recharge technologies. The optimization suggestions include: For mines with backward geothermal resource exploitation and utilization level, improve the “Three Rates” by adopting cascade utilization technology, accurately identifying geothermal reservoirs of recharge wells, and using large-diameter gravel-packed well completions, perforated well completions, and artificial reservoir reconstruction. Improve the evaluation index system, incorporate the degree of development and utilization into the geothermal resources exploitation and utilization level evaluation index system, optimize the characteristic index system, improve the fixed proportion grading method, and establish a special index system for non-heating mines. |
