Hot dry rock(HDR)is a kind of clean energy with significant *** the 1970s,the United States,Japan,France,Australia,and other countries have attempted to conduct several HDR development research projects to extract thermal energy by breaking through key ***,up to now,the development of HDR is still in the research,development,and demonstration *** HDR exploration borehole(with 236℃ at a depth of 3705 m)was drilled into Triassic granite in the Gonghe Basin in northwest China in ***,China geological survey(CGS)launched the HDR resources exploration and production demonstration project in *** three years of efforts,a sequence of significant technological breakthroughs have been made,including the genetic model of deep heat sources,directional drilling and well completion in high-temperature hard rock,large-scale reservoir stimulation,reservoir characterization,and productivity evaluation,reservoir connectivity and flow circulation,efficient thermoelectric conversion,monitoring,and geological risk assessment,*** the whole-process technological system for HDR exploration and production has been preliminarily established *** first power generation test was completed in November *** results of this project will provide scientific support for HDR development and utilization in the future.
