华东地区温度最高水热型地热井在山东东营钻成

Core Insights - The Shandong Provincial Geological and Mineral Bureau announced the successful drilling of the "Donggao Hot 1" geothermal well in the Dongying Yellow River Delta region, reaching a depth of 4002.17 meters with a bottom temperature of 162 degrees Celsius, making it the highest temperature hydrothermal geothermal well known in East China [1] Geothermal Resource Utilization - The geothermal well has a high thermal energy "grade," allowing for direct industrial applications such as geothermal power generation and providing stable industrial steam to enterprises [1] - The estimated stable thermal power output of the "Donggao Hot 1" well is 21.57 megawatts, with an annual heat release of 679,000 gigajoules, equivalent to approximately 27,000 tons of standard coal combustion [1] - If utilized for power generation, the well can produce about 25,200 kilowatt-hours daily, sufficient to meet the daily electricity needs of nearly 10,000 people [1] - Direct use of high-temperature steam in industrial production could provide approximately 94,000 tons of steam annually, replacing about 18,800 tons of standard coal and reducing carbon dioxide emissions by approximately 48,900 tons [1] Heating and Additional Applications - The high-temperature geothermal resource will still have a significant amount of tailwater at around 80 degrees Celsius, which can serve as a quality heat source for urban centralized heating [1] - Preliminary estimates suggest that the "Donggao Hot 1" well and its subsequent geothermal field can provide clean heating for nearly 2 million square meters of residential space after power generation [1] - The residual heat at around 60 degrees Celsius can be utilized for constructing large intelligent greenhouses and developing specialty aquaculture [1]
