摘要(Abstract)：

在松辽盆地东部断陷应用层序地层学方法识别地层超覆圈闭，预测了烃源岩层、储层和盖层。在此基础上对有利勘探区带进行了综合预测。松辽盆地东部断陷发育３个超层序、１１个层序，在３个超层序界面上共识别出地层超覆圈闭５４个，总面积４４６９９ｋｍ２；３个超层序中发育３套烃源岩层、４套储层和３套盖层。通过对构造圈闭叠合图、超覆圈闭叠合图以及与各套烃源岩、储层、盖层的匹配关系图的分析，认为松辽盆地东部断陷徐家围子西侧的安达—肇州背斜带是最有利勘探区带。
Hydrocarbon source rocks, reservoirs and seals are predicted through applying sequence stratigraphic method to the identification of stratigraphic onlap traps in the east rift of Songliao basin. On this basis, the favorable exploration areas are predicted comprehensively. Three supersequences, 11 sequences have developed in the east rift of Songliao basin. Fifty-four onlap traps, of which the total area is 4469.9km2, are identified on the interfaces of these 3 supersequences. Three sets of hydrocarbon source rocks, 4 sets of reservoirs and 3 sets of seals have developed in these 3 supersequences. According to the stacking chart of structural traps and onlap traps, and in relation to the matching charts of each set of hydrocarbon source rock, reservoir and seal, we can know that Anda-Zhaozhou anticlinal belt to the west of Xujiaweizi in the east rift of Songliao basin is the most favorable exploration zone.
