Yang Shi Wang·2025-12-21 09:56Core Viewpoint - China National Offshore Oil Corporation (CNOOC) announced that the cumulative oil and gas equivalent production of the Bohai Oilfield will exceed 40 million tons by 2025, setting a historical record [1]. Group 1: Bohai Oilfield Overview - The Bohai Oilfield is the largest offshore oilfield in China, having contributed over 600 million tons of crude oil to date [3]. - Established in 1965, the Bohai Oilfield is located in the Bohai Sea and consists of eight production operation areas: Liaodong, Liaobei, Bohan, Bozhong, Boxi, Pengbo, Qinhuangdao, and Caofeidian [4][6]. - The oilfield has over 200 operational oil and gas production facilities, including five shore power land switch stations and substations, and seven land terminals [8]. Group 2: Production and Technological Advancements - The Bohai Oilfield has more than 60 operational oil and gas fields, with an annual production exceeding 40 million tons and a cumulative crude oil production of over 600 million tons [10]. - As a core support area for offshore oil and gas development in China, the Bohai Oilfield has achieved breakthroughs in exploring and developing complex fields, including shallow sea conventional oil reservoirs and unconventional heavy oil [11]. - Since the implementation of the "Seven-Year Action Plan" for oil and gas reserve increase and production in 2019, the Bohai Oilfield has introduced innovative exploration theories and discovered six billion-ton-level oil and gas fields [12]. Group 3: Equipment and Innovation - The development of marine oil and gas resources relies heavily on high-end equipment, with significant growth in marine oil and gas equipment manufacturing during the 14th Five-Year Plan period, doubling the steel processing volume compared to the previous five years [13]. - The industry has transitioned from customized equipment to standardized, modular designs, enhancing construction efficiency by over 20% [14]. - The first marine oil and gas completion tool "smart factory" has been successfully launched, promoting the intelligent manufacturing of high-end marine completion tools [16]. Group 4: Future Projections - By 2025, the Bohai Oilfield is expected to complete seven capacity construction projects ahead of schedule by nearly 150 days, achieving a capacity construction acceleration of over 5% [20]. - According to the National Energy Administration, domestic crude oil production is projected to reach 215 million tons by 2025, with marine crude oil production expected to exceed 68 million tons, contributing approximately 80% of the total increase in national crude oil production [22].
