新时代地热资源勘查开发问题研究

Research on the Exploration and Development of Geothermal Resources in the New Era

摘要:

地热清洁能源的开发利用不仅可以实现节能减排、优化能源结构,而且还可带动相关设备制造、城镇清洁供暖、温泉小镇建设、特色生态农业、理疗休闲度假、旅游等相关产业。国家《地热能开发利用“十三五”规划》的发布,以及治理大气污染的现实需要,地热资源开发利用必将迎来一个快速发展期。因此,实现可持续、科学、合理规划利用是一个新的课题。本文从地热资源管理、开发利用、工程和地热温泉文化建设方面对相关问题进行了研究与思考。建议加强政策引导,规划统一管理,加强监管,并重视宣传和科普,主动作为,以提升新时代地质工作的服务能力和作用地位。技术方面,应加大深井换热系统的技术研究；在地层条件允许情况下优先选择空气钻井(孔)和泵吸反循环钻井工艺；开展高强度、耐腐蚀、导热性好的新型成井管材的研发。

Abstract:

The development and utilization of clean geothermal energy can not only achieve energy saving & emission reduction and optimize energy resource structure, but also drive related equipments manufacturing, urban clean heating, hot spring town building, characteristic ecological agriculture, physical therapy and leisure vacation, tourism and other related industries. With the issuance of “The development and utilization of geothermal energy ‘13th Five-year’ Plan” as well as the practical needs of controlling air pollution, there will be a rapid development period of geothermal resources development and utilization. Therefore, sustainable, scientific and reasonable planning utilization of energy will be a new topic. This paper studies the related issues in geothermal resources management, development and utilization, engineering and hot springs cultural construction. It is suggested by strengthening policy guidance and supervision, carrying out unified management and paying attention to publicity and science popularization to enhance the service ability and role of geological work in the new era. In terms of technology, the technology research should be strengthened on deep well heat exchange system, air drilling and pump suction reverse circulation drilling technologies should be preferred under the permissible geological conditions, development of new type tubing with high strength, corrosion resistance and good thermal conductivity should be carried out.
