第七个！我国渤海再获亿吨级油田

Core Insights - The discovery of the Qinhuangdao 29-6 oil field marks the seventh billion-ton oil field found in the Bohai Sea since 2019, reinforcing China's offshore oil and gas resource reserves and its energy security [1][4]. Group 1: Discovery Details - The Qinhuangdao 29-6 oil field is located in the central Bohai Sea, approximately 44 kilometers west of Jingtang Port, and is the second billion-ton lithologic oil field discovered in the Shijiu Tuo uplift area [3][4]. - The discovery well encountered an oil layer of 66.7 meters and reached a total depth of 1,688 meters, with a single well production capacity of approximately 370 tons of crude oil per day, indicating promising exploration prospects [3][4]. Group 2: Exploration Insights - The Shijiu Tuo uplift has historically been a challenging area for oil exploration, with previous efforts yielding unsatisfactory results since the 1970s due to the lack of major fault seals that hindered oil accumulation [3][4]. - Recent advancements in understanding the oil migration pathways and the identification of "invisible" lithologic traps have led to successful exploration in the slope zone of the Shijiu Tuo uplift, challenging traditional beliefs about oil accumulation in this area [4]. Group 3: Implications for Energy Security - The successful discovery of the Qinhuangdao 29-6 oil field emphasizes the importance of refined exploration techniques and contributes to the resource foundation necessary for stabilizing energy supply, particularly in supporting the coordinated development of the Beijing-Tianjin-Hebei region [4].
