Core Viewpoint - The successful drilling of the "Donggao Hot 1" geothermal well in East China marks a significant achievement in the exploration and utilization of hydrothermal geothermal energy, which can provide substantial energy resources for various applications [1][2]. Group 1: Geothermal Energy Overview - Geothermal energy can be categorized into magma-type, dry hot rock-type, and hydrothermal geothermal energy, with hydrothermal being the primary focus for global development [2]. - The "Donggao Hot 1" well, with a depth of 4002.17 meters and a bottom temperature of 162°C, is expected to release an annual heat equivalent to approximately 27,000 tons of standard coal [1]. Group 2: Technological Advancements - The drilling team developed high-temperature acid fracturing technology to address challenges in deep geothermal reservoirs, enhancing connectivity and preventing blockages [3]. - A submersible pump was also developed to operate stably at 146°C, overcoming limitations in high-temperature pumping equipment [3]. Group 3: Implications for Energy and Society - The successful drilling challenges the traditional belief that high-temperature geothermal resources are limited to specific regions, opening opportunities for similar geological areas [4]. - Geothermal energy applications include clean urban heating, electricity generation, industrial production, and agricultural uses, emphasizing a smart, tiered utilization approach [5][6]. - The development of deep geothermal resources aims to benefit the public, with potential to replace traditional fossil fuels and contribute to a low-carbon future [6].
