Investigation on the Technological Characteristics of Geothermal Resources in the Qinzhou Chenzhou Fault Zone

The Qinzhou Chenzhou Fault Zone is the junction zone between the Huaxia Block and the Yangtze Block. It is of great significance for how geothermal resources are controlled and for in-depth research on structural heat control. Starting from geothermal geological analysis, this article systematically analyzes and studies the types of thermal reservoirs, hot spring distribution, spring temperature field distribution, spring flow field distribution, and spring chemical field distribution on both sides of the Qinzhou Chenzhou Fault Zone. The results indicate that the Qinzhou Chenzhou fault zone has a significant controlling effect on geothermal resources in the Hunan Guangxi region. The northwest side of the fault zone is dominated by sedimentary thermal reservoirs, while the southeast side shows a decrease in the distribution of sedimentary thermal reservoirs, which is basically equivalent to intrusive rock structure thermal reservoirs; The anomalous thermal field of the springs is distributed along the Qinzhou-Chencheng fault zone, with a significant difference in the density of hot springs on either side of the fault, The density of hot springs on the northwest side of the fault zone is 1.18/104km², which is lower than that on the southeast side, which is 3.69/104km²; The chemical correlation coefficients of the three high-temperature hot springs are 0.78-0.8.
