The drilling goal of Fushen-1 Well is granite dated 250 million years ago. Since the exploration was launched in August 2023, Sinopec has adopted multiple independently developed innovative technologies, including the combination of dual-drive drilling and high-pression injection, to reach the temperature limit of hot dry rock stipulated by the national energy industry standards, while forming the key technologies of detection and evaluation of deep geothermal resources.
Next, Sinopec will carry out extensive research and field tests at Fushen-1 Well to establish the first platform integrating research, education, and experimentation of deep geothermal in South China, and explore to formulate theoretical methods and technical systems applicable to the region and help China to achieve the "Dual-Carbon" goal.
The development and application of deep geothermal has promising prospects, as a stable, reliable, green, and low-carbon renewable energy resource, it has the advantages of large reserves, wide distribution, and is environmentally friendly.
According to China's geological surveys, the hot dry rock geothermal resources within the range of 3 kilometers to 10,000 meters underground in China's land area are equivalent to 856 trillion tons of standard coal, and if only 2 percent of them are extracted, they can reach 2,993 times the annual energy consumption of China in 2023.
