Core Viewpoint - The "Deep Sea No. 1" Phase II project has been fully put into production, making it China's first deep-water high-pressure gas field, with an expected annual gas production exceeding 4.5 billion cubic meters, positioning it as the largest offshore gas field in the country [1][4]. Group 1: Production and Capacity - The "Deep Sea No. 1" gas field has achieved full production with 23 underwater gas wells, capable of supplying over 15 million cubic meters of natural gas daily to the Guangdong-Hong Kong-Macao Greater Bay Area and Hainan [4]. - The gas field has geological reserves exceeding 150 billion cubic meters, with a maximum operational water depth of over 1,500 meters and a maximum formation temperature of 138 degrees Celsius [7]. Group 2: Technological Advancements - The project has overcome significant challenges related to "deep water, deep layers, high temperature, and high pressure," introducing a new development model that utilizes a deep-water semi-submersible platform for remote-controlled underwater production systems [10]. - Innovations have led to the establishment of a comprehensive design system for China's independent development of deep-water oil and gas resources, addressing world-class technical challenges [10]. Group 3: Equipment Development - China has developed a series of large deep-sea oil and gas equipment, including "Deep Sea No. 1," "Sea Base Series," and "Sea Aster No. 1," enhancing its capabilities in deep-water engineering [11]. - The country has also made breakthroughs in critical equipment development, contributing to the advancement of 3,000-meter-class deep-water engineering vessels [11]. Group 4: Future Outlook - In 2024, China's marine energy supply is expected to continue growing, with marine crude oil and natural gas production projected to increase by 4.7% and 8.7% year-on-year, respectively [13].
