中国石化已完成我国最深地热探井——海南富深1号井的钻探，井深5200米。这一里程碑揭示了华南深层地热的形成和富集。干热岩在人口区域和深度上的突破，对于加强华南地热资源规模开发利用、助力能源结构调整具有重要意义。

抚神一号的钻探目标是2.5亿年前的花岗岩。自2023年8月勘探启动以来，中国石化采用了双驱动钻井与高精度注入相结合等多项自主研发的创新技术，达到了国家能源行业标准规定的干热岩温度极限。

下一步，中国石化计划在抚神一号开展广泛的研究和现场试验，建立华南地区首个深层地热研究、教育和实验为一体的平台。还将探索制定适合本地区的理论方法和技术体系，助力我国实现“双碳”目标。

深层地热作为一种稳定、可靠、绿色、低碳的可再生能源，开发利用前景广阔。具有储量大、分布广、环境友好等优点。

据我国地质调查显示，我国国土面积地下3公里至10000米范围内的干热岩地热资源相当于856万亿吨标准煤。如果仅提取其中的2%，那么到2023年，它们就可以达到中国年能源消耗量的2993倍。

Sinopec has completed drilling China’s deepest geothermal exploration well, the Fushen-1 well in Hainan, with a depth of 5,200 m. The milestone revealed the deep geothermal formation and enrichment in South China. The breakthrough in hot dry rock in terms of demographic region and depth is of great significance to enhance the large-scale development and utilization of geothermal resources in South China and aid the energy structure adjustment.

The drilling goal of Fushen-1 was granite dated 250 million years ago. Since the exploration launched in August 2023, Sinopec has adopted multiple independently developed innovative technologies, including the combination of dual-drive drilling and high-precision injection, to reach the temperature limit of hot dry rock stipulated by the national energy industry standards.

Next, Sinopec plans to carry out extensive research and field tests at Fushen-1 to establish the first platform integrating research, education and experimentation of deep geothermal in South China. It will also explore to formulate theoretical methods and technical systems applicable to the region and help China 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 km to 10,000 m underground in China’s land area are equivalent to 856 trillion tons of standard coal. If only 2% of them are extracted, they can reach 2,993 times the annual energy consumption of China in 2023.
