海上稠油规模化开发实现重大突破

Core Insights - China National Offshore Oil Corporation (CNOOC) has achieved significant progress in the large-scale application of offshore heavy oil thermal recovery technology, with cumulative production exceeding 5 million tons, making China the first country to realize large-scale thermal recovery of offshore heavy oil [1][2] Group 1: Industry Overview - Heavy oil, characterized by high viscosity, density, and poor flowability, poses significant extraction challenges, especially in offshore environments where operational space is limited and costs are high [1] - Approximately 70% of the remaining global oil resources are heavy oil, making it a primary focus for oil-producing countries aiming to increase production [1] Group 2: Technological Advancements - CNOOC has developed the "few wells, high yield" thermal recovery theory and associated high-efficiency lifting processes to enhance single well production, addressing issues of low thermal recovery capacity and significant heat loss [2] - The company has successfully created world-leading equipment capable of withstanding 350°C for integrated injection and production, along with other innovative technologies such as a mobile thermal injection platform [2] Group 3: Production Capacity and Future Outlook - The current offshore heavy oil thermal recovery is primarily concentrated in the Bohai Sea, with major thermal recovery oil fields established, and production is expected to reach 200,000 tons for the year [1] - CNOOC anticipates that thermal recovery production will exceed 1 million tons for the first time in 2024, indicating a rapid acceleration in production capacity [2]
