Country Session 4: China

In recent years, great progress has been made in China’s deep-sea oil and gas engineering technology and gas hydrate pilot production. This session will focus on the new development in these technologies and discuss China’s natural gas development strategies under "Dual Carbon" goals. Topics to be discussed include:

•R&D progress of China’s deepwater oil and gas equipment: The world's first 0.1-million-ton deep-water semi-submersible production platform "Deep Sea No. 1" energy station independently developed and built by China has been put into operation. With a designed fatigue life of 150 years, the energy station is able to withstand a once-in-a-hundred-year super typhoon. It is equipped with nearly 200 sets of key oil and gas processing equipment and is the world’s first semi-submersible platform stand column with a maximum oil storage capacity of nearly 20,000 cubic meters.

•New technologies for China’s offshore oilfield engineering: Faced with geological factors such as deep, poor conditions and loose soil of South China Sea, drilling in shallow formations in deep water areas is difficult and risky. Accidents such as wellhead instability and wellbore abandonment occur frequently, bringing huge challenges and losses. In recent years, major breakthroughs have been made in the drilling design, key technologies in operation control and key logging and drilling equipment of the above-mentioned formations, playing a key role in deep-water drilling in South China Sea.

•Current status and challenges of hydrate development in China: China has made historic breakthroughs in the pilot production of natural gas hydrates, yet with difficulties and bottlenecks in achieving the goal of "2035 highly efficient natural gas hydrate development". Natural gas hydrate development strategies, roadmap, and key direction for technologies will therefore be discussed.

•China’s natural gas development path under “Dual Carbon” goals: Based on the analysis of the two stages of "Dual Carbon" goals, challenges and principles, the opportunities, advantages and constraints of China's natural gas development will be deeply analyzed together with the discussion of how to accelerate the development of natural gas in "Carbon Peak" as the main energy and its approach as a transition energy in “Carbon Neutrality”.
