Abstract
With the continuous acceleration of the exploration and development progress of geothermal (hot dry rock) resources, the workload of geothermal resource investigation and drilling has increased sharply, but the research and application of comprehensive logging technology is relatively lagging behind in China. This article analyses the response relationship of various logging data to geothermal geological conditions item by item, introduces the development and application status of logging technology at home and abroad, and takes HR-1 well as an example to give a brief introduction and analysis of the comprehensive logging technology. Theory and practice have proved that the comprehensive logging can provide an important reference and scientific basis for the evaluation of the potential of geothermal reserves. The development and application status of the geothermal logging technology in China can no longer meet the needs of geothermal resource exploration and development. It is imperative to carry out in-depth research on geothermal logging technology and further increase its application.
