中国海油在渤海湾盆地获勘探重大突破

Core Insights - China National Offshore Oil Corporation (CNOOC) has achieved a significant breakthrough in the exploration of Paleogene lithology in the Liao Zhong depression of the Bohai Bay Basin, successfully drilling high-yield oil and gas wells, which strengthens the foundation of offshore oil and gas resource reserves in China [1][2] Group 1: Exploration Achievements - The JZ27-6-3 well encountered a 57.4-meter oil and gas layer and was drilled to a total depth of 1,925 meters, yielding approximately 500 tons of crude oil and 20,000 cubic meters of natural gas per day [1] - The Liao Zhong depression has complex oil and gas reservoir structures, and this area had not seen large-scale exploration discoveries for many years [1] Group 2: Technological Innovations - CNOOC's research personnel have conducted continuous technical breakthroughs, establishing a coupling relationship between sediments and uplifts, and innovatively proposing a favorable migration model for Paleogene lithology, addressing the challenges of large-scale accumulation in Paleogene lithology [1] Group 3: Strategic Implications - The breakthrough in the Liao Zhong depression confirms the significant exploration potential of Paleogene lithology oil and gas reservoirs in the Bohai Bay Basin, promoting the secondary exploration process in old oil fields and providing replicable technical routes and practical experiences for similar exploration in China's offshore areas [1]
