摘　　要：大港油田断层发育,地质情况复杂,寻找更多的非构造油气藏为现阶段主要任务。在此背景下,研究断块区的岩相古地理环境,对寻找隐蔽的非构造油气藏有重要意义。歧口凹陷作为黄骅坳陷中的二级构造单元,在古近纪经历了断陷期的发展到消亡,在断陷构造的各地质时期,歧口凹陷区特有的岩相古地理环境,形成了大量的岩性地层圈闭。基于歧口凹陷的岩相古地理条件,从岩性圈闭的形成因素出发,以歧口凹陷滨海斜坡区为实例,探讨在岩性地层圈闭发育区获得高产井的可行性。There are various and abundant faultblock in Dagang oilfield with complex geological condition.Under this back-ground,carring on research on fault block lithofacies and pa-leogeography has very important meaning to locating more non-tectonic reservoirs.Qikou sag in Huanghua depression is secondary building unit.In an era of Paleogene,it went though the period of developing to extinction.Abundant li-thologic trap has been formed in the various geological period under Qikou sag unique lithofacies and paleogeography envi-ronment.In this article,Qikou sag unique lithofacies and paleogeography condition and the factors on which hthologic trap formed have been considered,Qikou sag coastal slope has been set as an example,the the probability of high-yield well in lithological trap developing area has been dis-cussed.
