渤海油田再获亿吨级大发现

Core Insights - China National Offshore Oil Corporation (CNOOC) has made a significant discovery of a billion-ton oil field, Qinhuangdao 29-6, in the Bohai Sea, marking the seventh billion-ton oil field discovered since 2019 in this region, which is crucial for enhancing China's offshore oil and gas resource reserves and ensuring national energy security [1][2] Group 1 - 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 [1][4] - The discovery well encountered an oil layer of 66.7 meters and was drilled to a depth of 1,688 meters, with a single well production capacity of approximately 370 tons of crude oil per day, indicating promising exploration prospects [1][4] - The discovery is a result of refined exploration strategies that identified "invisible" lithologic traps in the oil migration pathways, leading to the successful identification of oil-rich areas in the previously challenging Shijiu Tuo uplift slope [4][5] Group 2 - The Qinhuangdao 29-6 oil field discovery reinforces the value of meticulous exploration and is expected to solidify the resource foundation for increasing domestic oil reserves and production, contributing to energy stability and supporting the coordinated development of the Beijing-Tianjin-Hebei region [5]
