南黄海盆地海相中—古生界油气资源潜力巨大

GREAT RESOURCES POTENTIAL OF THE MARINE MESOZOIC-PALEOZOIC IN THE SOUTH YELLOW SEA BASIN

南黄海盆地不仅是扬子地台在海域的延伸,而且是下扬子地块的主体。南黄海盆地中—古生代海相沉积建造与四川盆地相似,具有与威远、安岳、五百梯、焦石坝、普光、龙岗等大型、特大型油气田相同的含油气层位,发育3套区域性烃源岩和3套完整的生储盖组合,油气资源潜力巨大。崂山隆起是海相下古生界的油气远景区,勿南沙隆起是海相中—古生界的油气远景区。

The South Yellow Sea Basin is not only the seaward extension of the Yangtze Platform,but also the main part of the Lower Yangtze Platform.The Mesozoic-Paleozoic marine sequences there is similar to those in the Sichuan Basin and the oil-gas bearing horizons are accordant with those in the large oil-gas fields in Sichuan Basin,such as the Weiyuan,Anyue,Wubaiti,Puguang and Longgang gas fields.There are three sets of source rocks and three source-reservoir-cap assemblages in the South Yellow Sea Basin.The Laoshan Uplift is the most promising region for oil and gas prospect in the marine Lower Paleozoic,while the Wunansha Uplift is the most promising region for oil and gas prospect in the marine Mesozoic-Paleozoic.
