摘　　要：干热岩(HDR)地热资源是一种极具竞争力的清洁可再生能源,其资源潜力大,安全环保,越来越受到各国能源战略的关注。欧美国家的成功实践说明了干热岩开发的可行性,但中国干热岩的研究较晚,目前还处于靶区圈定和科学钻探阶段,但有了初步的勘探成果。通过对国内外干热岩资源的综合研究,本文阐述了干热岩资源的赋存指标,并将中国干热岩资源的赋存类型分为高放射性产热型、沉积盆地型、近代火山型和强烈构造活动带型。结合中国干热岩的钻探开发,提出了在干热岩钻井时的困难与勘查开发的技术要求和进展。本文旨在通过综合分析,尽快解决目前的难点,促进中国干热岩资源的有效利用。The hot dry rock(HDR)geothermal resource,which is safe and green,is a highly competitive renewable clean energy with great resource potential.More and more attention have been paid to it by energy strategy of various countries.And the successful practice of European and American countries has shown the feasibility of HDR development.However,the research of HDR in China is still in the stage of target delineation and scientifi c drilling with just preliminary exploration results.Based on a comprehensive study of HDR resources at home and abroad,this article elaborates the occurrence indicators of HDR resources,and divides the occurrence types of HDR resources in China into four types,i.e.the high radioactive heat production type,the sedimentary basin type,the modern volcano type and the intraplate active tectonic zone type.By examining the drilling situation of HDR in China,the paper identifi es the diffi culties in drilling HDR as well as the technical requirements and progress of exploration.The comprehensive study is intended to help solve the current diffi culties as soon as possible,and promote the eff ective development of hot dry rock resources in China.
