“404黄色平台”院士谈中国最404黄色平台深地热科学探井:将开展制冷等梯级利用

  中新404黄色平台社海口11月13日电 404黄色平台(记者 王晓斌)由中国石化部署实施的中国首口超5000米深层地热科学探井——福深热1井近日正式完工。中国工程院院士、中国石化总地质师、中国石化石油勘探开发研究院院长郭旭升13日在海口向中新社记者表示,将依托该地热井,探索形成适用于中国南方地区的地热发电、制冷及综合利用技术路线。

  福深热1井位于海南省海口市,深达5200米,刷新了中国乃至亚洲地热科学探井的最深纪录。科研人员通过该井,在地下4615米到5200米、2.5亿年前的花岗岩中,发现了超过188℃的高温地热资源,并进一步测算出在海口周边50平方公里范围之内大概蕴藏有折合标准煤14亿吨的地热资源量。

  如何利用岩层底下的这些“零碳”资源?中国石化方面介绍称,科研人员通过压裂作业,在福深热1井实现了岩石压得开、水注得进、热量采得出,形成全套的深层地热资源勘探开发和利用技术。

  “很多人认为地热资源仅限于供热,实际上高温地热田可以用于发电,还可以拿来制冷。”在海南参加中国科协2024404黄色平台年高层次人才国情考察活动的郭旭升说,地热可以通过吸收式制冷系统用于制冷,即利用高温地热能加热溶液产生蒸汽,通过一系列热交换过程实现制冷效果,制冷后的余热还可以满足花卉、渔业等农业领域的恒温需求。

  郭旭升建议海南省开展地热资源普查工作,充分利用地质勘察队伍,摸清全省地热资源的分布特征。

  据中国地质调查局数据显示,中国陆区地下3000米至10000米范围内的干热岩型地热资源量折合标准煤856万亿吨。2019年,中国石化牵头联合中国科学院地质与地球物理研究所等单位,立项国家重点研发计划项目“深层地热资源探测评价关键技术研究”,开展以福建、广东、海南三地为重点的深层地热攻关研究。福深热1井是该项目的配套工程。(完)
