According to Sinochem News, at the 2025 National Petroleum and Chemical Industry Science and Technology Innovation Conference held on December 24, Li Yunpeng, Secretary of the Party Committee and President of the China Petroleum and Chemical Industry Federation, summarized the overall innovation achievements of the industry since the 14th Five-Year Plan period. In terms of ensuring **energy security**, the development of the “Deep Sea No.1” ultra-deep-water gas field has seen historic advancements in key technologies and their applications, marking China as the third country in the world to possess the capability to develop ultra-deep-water oil and gas resources independently. A mobile field rock sample in-situ integrated continuous measurement imaging system has achieved a major breakthrough for logging technology, going from scratch to a functional solution. The drilling fluid technology for ultra-deep wells of 10,000 meters played a crucial role in ensuring the successful completion of China’s first 10,000-meter deep well, Shendi Tako-1 Well, serving as an essential technical tool for drilling at such great depths. In driving the industry forward to higher levels, Sinopec’s breakthroughs in advanced ethylene technology and their industrialization have enabled China to break the foreign monopoly on ethylene technology, and it has taken the lead in the world in fully mastering the cracking technologies for light feedstocks, heavy feedstocks, and feedstocks with high olefin content. The development of key technologies for high-quality hexamethylenediamine via the caprolactam method and its industrialization have opened up new applications for caprolactam products, while enhancing the autonomy and control over the industrial chain as well as the security of the supply chain. The green synthesis technology for vitamin D3 series products has filled the international gap in the chemical production of 25-hydroxyvitamin D3, enabling the establishment of a complete vitamin D3 industry chain. In promoting green and low-carbon development, multi-enzyme synergistic catalysis systems, as well as innovations in green manufacturing technologies for bio-based products, have enabled the development of cost-effective, large-scale, and clean production processes for bulk chemicals. New micro-nano mass transfer enhancement technologies for large-scale multiphase reaction processes have been applied on a large scale in production facilities for hydrogenation at the million-ton level, carbonylation and air oxidation at the hundred-thousand-ton level, breaking the monopoly of international giants in various product sectors. In terms of improving the level of equipment autonomy, the design, manufacturing, and maintenance technologies for long-life large-scale ethylene cracking reactors have made significant contributions to the construction of major ethylene production facilities on a million-ton scale as well as to the safe and stable operation of such cracking units. A green separation method and complete set of equipment for stirred alkylization of sulfuric acid have revolutionized traditional alkali washing and water washing processes, enabling a green and low-carbon transformation.
