老油田新发现！渤海湾盆地油气勘探获重大突破

Core Insights - China's offshore oil and gas exploration has achieved significant breakthroughs, particularly in the Bohai Bay Basin's Liaozhong Depression, with the successful drilling of high-yield oil and gas wells [1][3] - The JZ27-6-3 well encountered a 57.4-meter oil and gas layer and reached a total depth of 1,925 meters, producing approximately 500 tons of crude oil and 20,000 cubic meters of natural gas per day [1][3] Exploration Achievements - The region's complex oil and gas reservoir structure had previously hindered large-scale exploration, but China National Offshore Oil Corporation (CNOOC) has made technological advancements to address these challenges [3] - CNOOC established a coupling relationship between sediments and uplifts, innovating a model for the advantageous migration of Paleogene lithologic bodies, which led to the identification of rich oil and gas accumulation zones [3] Strategic Implications - The breakthrough in the Liaozhong Depression confirms the substantial exploration potential of Paleogene lithologic oil and gas reservoirs in the Bohai Bay Basin, facilitating secondary exploration in older oil fields [3] - This discovery is crucial for ensuring stable energy supply in the Beijing-Tianjin-Hebei region and the surrounding Bohai Sea area, while also providing replicable technical routes and practical experiences for similar explorations in China's maritime regions [3]
