干热岩发电发展现状与挑战

Development Status and Challenges of Hot Dry Rock Power Generation

我国干热岩资源丰富,发电潜力巨大,理应在以新能源为主体的新型电力系统中占据一席之地。然而,目前国内干热岩开发利用程度较低,尚无干热岩发电项目成功运行并网。为此,该文回顾了国内外干热岩发电技术的发展现状及存在问题,进而探讨了未来干热岩发电应重点突破高温钻井、大型储层构造及高效换热等技术难题,最后提出我国应通过加大政策扶持与研发投入、加强国际交流合作等途径来促进干热岩发电在我国碳中和进程发挥重要作用。

China is rich in hot dry rock resources and has huge power generation potential,and it should occupy a place in the new power system with new energy as the main body.However,at present,the degree of the development and utilization of hot dry rock in China is relatively low,and the project of hot dry rock power generation has not been successfully operated and connected to the grid.Therefore,this paper reviews the development status and existing problems of hot dry rock power generation at home and abroad,then discusses that hot dry rock power generation should focus on the breakthrough of technologies in high-temperature drilling,large-scale reservoir structure and efficient heat exchange in the future,and finally proposes that China should increase policy support and research and development investment and strengthen international exchanges and cooperation to promote hot dry rock power generation to play an important role in China's carbon neutralization process.
