Prospects and problems of geothermal resources exploitation and utilization in Tianjin

摘要: 在全面落实国家“双碳”目标的大背景下,地热资源高质量开发利用已愈来愈重要。天津地热资源禀赋好,开发利用已初具规模,但利用仍然较为粗放,没有形成集约型全产业链发展模式,仍需在资源勘查、地热回灌、动态监测和科学管理等方面全面提升。文章分析了当前天津地热资源开发利用现状和存在问题并提出具体工作措施和建议,未来应加大天津地热资源的整装勘查力度,摸清6 000 m以浅地热资源家底,保障资源供给,分区分层确定开采方案;协同攻关地热资源回灌关键技术,在地热资源承载力评价基础上,加大回灌力度,提升资源利用效率;同时做好技术规范和法规标准制定,建成地热资源监测一张网,利用监管机制创新和信息化手段提升管理水平;加大政府扶持力度,“放管服”相结合,开辟多元化融资渠道,保障地热资源勘查开发资金,促进地热产业健康有序融合发展。Abstract: Under the background of the full implementation of the national"dual carbon"goal, the high-quality development and utilization of geothermal resources has become more and more important.There is a good endowment of geothermal resources and large-scale development and utilization in Tianjin.However, the utilization of geothermal resources in Tianjin is still extensive and the intensive development model has not been formed.It still needs to comprehensively improve resources exploration, geothermal recharge, dynamic monitoring and scientific management.This paper analyzes the present situation and existing problems of geothermal resources in Tianjin, and also comes up with targeted policies and measures for sustainable exploitation of geothermal resources in a systematic way.It is supposed to strengthen the integrated exploration of shallow geothermal resources with a depth of 6 000 m, ensure the supply of resources and determine the exploitation scheme by zoning and stratification, collaborate to tackle key technologies of geothermal resource recharge, increase the intensity of irrigation and so on.At the same time, it is necessary to improve management and policies by innovativing supervision mechanisms, increase government support by combining"delegating power, delegating regulation and providing services"and open up diversified financing channels.Ultimately, we hope to promote a healthy and orderly integrated development of the geothermal industry in Tianjin.
