江苏如东发现近110℃地热资源 刷新东南沿海地热勘查开发纪录

Core Insights - The "Jiangsu Province Key Areas Clean Geothermal Energy Efficient Comprehensive Utilization Demonstration" project has made significant progress with the successful completion of the "Yangshen 1 Well," reaching a depth of 3501.66 meters, setting a record for the deepest water-thermal geothermal well in Jiangsu Province [1] - The well recorded a bottom temperature of 112.82℃ and a thermal storage (water) temperature of 108.96℃, with a daily water output exceeding 4080 cubic meters, establishing new records for geothermal exploration in Southeast coastal regions of China [1] Project Details - The project utilizes self-developed "Thermal Wave Resistance" well positioning technology and an industry-leading "surface turntable + downhole screw drill" composite rotary drilling process, overcoming multiple technical bottlenecks associated with traditional methods [1] - The project has identified the thermal storage structure and thermal control (water) features of geothermal resources within 5 kilometers of Xiaoyangkou, precisely delineating 10 thermal control (water) fault zones and predicting 4 favorable thermal storage segments [1] - The successful selection of the well site for the 3500-meter deep geothermal well (Yangshen 1) and the completion of three core sampling rounds have been achieved [1] Future Plans - The Jiangsu Provincial Geological Survey and Research Institute will further promote the application of these results to provide energy resource assurance for the subsequent construction of geothermal power stations [1] - The project aims to lay the foundation for exploring integrated utilization technology routes suitable for Eastern China, including "power generation - heating/cooling - facility agriculture" [1]
