摘　　要：干热岩是战略性清洁能源,属于固体矿产范畴,其赋存条件受控于地质环境。在河南省干热岩资源调查项目基础上,结合国内外干热岩成藏特征和钻探成果综合研究分析认为:河南省干热岩热源主要以侵入岩体热传导和地幔热传导(深部隐伏断裂对流热传导)2种模式;其成藏环境必须具备巨大的稳定的高导热性岩体、巨厚的稳定的低导热性上覆盖层和深部热源3个基本条件。针对目前干热岩资源找矿理论和钻探存在的问题,提出了河南省干热岩初步找矿方向和建议,明确了加大钻探技术和工艺研发的重大意义。Hot dry rock,a strategic clean energy resource,belongs to the category of solid minerals,and its occurrence conditions are controlled by the geological environment.With the execution of the hot dry rock resource survey project in Henan Province,and the comprehensive study of hot dry rock reservoir-forming characteristics and drilling results at home and abroad,it is inferred that the heat source of hot dry rock is mainly composed of two modes:the heat transfer of intrusive rock mass and the heat transfer of mantle(convective heat transfer of deep buried faults).The reservoir⁃forming environment must have three basic conditions:huge and stable high thermal conductivity rock mass,thick and stable low thermal conductivity overburden and heat source.In view of the existing problems in the prospecting theory and drilling for hot dry rock resources,the preliminary prospecting direction and suggestions are put forward.
