| Abstract: | In recent years,the exploration and development of hot dry rock has become a hot spot in academic circles.In order to understand the mechanism of heat accumulation and conduction in hot dry rocks,an experiment of rock triaxial thermal conductivity was carried out by sorting out and summarizing previous research results and combining theoretical methods such as structural geology,heat transfer,geothermal science and mineral petrology.The results show that there is a difference in the triaxial thermal conductivity of rocks,which leads to the anisotropy of the conduction of underground heat flow in rocks.Therefore,the anisotropic index of rock thermal conductivity and the heat transfer formula of hot dry rock are proposed,and the heat transfer law and aggregation characteristics of hot dry rock are analyzed,and the vertical structural combination of heat source,heat channel,hot dry rock reservoir and cap layer is beneficial to the heat enrichment of hot dry rock. |
