山东东营钻成华东地区温度最高“水热型”地热井

Core Insights - The recent breakthrough in deep high-temperature geothermal resource exploration in the Yellow River Basin, Shandong Province, has been announced, highlighting significant geological survey achievements and the successful drilling of the Donggao Hot 1 geothermal well [1][5]. Geothermal Resource Exploration - The geological survey covered approximately 4,000 square kilometers, with the Donggao Hot 1 well reaching a depth of 4,002.17 meters and recording a bottom temperature of 162 degrees Celsius, with a wellhead water temperature of 138 degrees Celsius and a single well water output of 101.3 cubic meters per hour [1][2]. - The project has established a comprehensive technical system for geothermal resource exploration, including precise detection, efficient drilling, thermal energy utilization, tailwater reinjection, monitoring and early warning, and smart management [2]. Economic and Social Impact - The discovered high-temperature geothermal resources are expected to generate an annual economic benefit of approximately 450 million yuan, benefiting around 180,000 urban and rural residents [6]. - The development aims to provide tangible benefits to the public, with plans for multi-scenario utilization of geothermal energy, including green power generation, industrial steam, urban heating, facility agriculture, and aquaculture [5][6]. Future Development Plans - The Shandong Provincial Geological and Mineral Exploration Bureau plans to continue exploration efforts to enhance the accuracy of geothermal resource assessments in the Dongying Yellow River Delta region and broaden application scenarios [6]. - The focus will be on a model that involves government leadership, geological support, enterprise participation, and demonstration projects to diversify the applications of geothermal resources [6].
