摘　　要：大港探区断层发育,地质情况复杂。研究断块区的岩相古地理情况,对寻找隐蔽的非构造油气藏具有重要意义。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。文中着眼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,探讨了在岩性-地层圈闭发育区获得高产井的可行性。Fault block developed well in Dagang Oilfield, so the geology is complex. The research on the petrofacies and paleogeography in fault block region is significant for finding non-structural reservoir. A great number of lithostratigraphy traps formed in Qikou Sag due to the special petrofacies and paleogeography. Based on the petrofacies and paleogeography conditions, combined with the factors for lithologic trap forming, the probability of obtaining high productivity well in Binhai slope region in Qikou Sag is discussed.
