摘　　要：石油和天然气资源的短缺已经严重制约了中国国民经济的发展,开拓油气勘探新领域和寻找后备油气基地已经上升为国家战略。以近些年海洋区域调查实测资料为基础,结合前人研究成果,对中国东部海域重点盆地构造特征和演化过程进行研究,分析各盆地油气成藏要素和成藏条件,并指出有利勘探区域。研究表明:按照盆地发育位置和成因,中国东部海域沉积盆地可划分为2种类型;受块体之间相互作用的控制,各盆地经历了不同的构造演化历史,发育明显不同的构造和地层特征,进而导致油气成藏要素和成藏模式截然不同;渤海湾盆地油气资源主要赋存于古近系中上部、新近系下部和前新生界潜山,北黄海盆地勘探重点是东部坳陷中生界,南黄海盆地应以中—古生界海相油气勘探为重点,东海陆架盆地则应兼顾中生界和新生界油气勘探。研究结果可以为中国东部海域沉积盆地油气勘探提供一定的参考。The shortage of oil and natural gas resources has seriously restricted the development of China's national economy.Exploring new areas of oil and gas exploration and searching for reserve oil and gas bases have become a national strategy.Based on the data obtained from marine regional surveys and combined with previous research results,we studied the structural characteristics and evolution process of these basins,analyzed the factors and conditions of hydrocarbon accumulation in each basin,and pointed out the favorable exploration areas in the eastern China seas and the adjacent areas.According to the location and genesis of basins,sedimentary basins in the eastern China seas region can be divided into two types.Controlled by the interaction between blocks,basins have undergone different tectonic evolution stages,developed different structural and stratigraphic characteristics,which lead to distinct differences in hydrocarbon accumulation factors and modes.Oil and gas resources in Bohai Bay Basin mainly accumulated in the Middle-Upper Paleogene,the Lower Neogene and the buried hill of Pre-Cenozoic.The North Yellow Sea Basin should be focused on the Mesozoic of the Eastern Depression.The exploration in the South Yellow Sea Basin should be focused on the Mesozoic-Palaeozoic marine oil and gas exploration.The oil and gas exploration in the East China Sea Shelf Basin should consider both Mesozoic and Cenozoic strata.This study provided a reference for oil and gas exploration in sedimentary basins in the eastern China offshore basins.
