摘　　要：笔者运用高分辨率层序地层学理论和分析方法,利用钻井、测井及三维地震资料对三角洲内部基准面旋回的各种界面识别,进行基准面旋回的划分和对比研究,最后分析三角洲各期基准面旋回和浊积砂体的分布规律,从而对东营三角洲的岩性油气藏进一步勘探提供一些科学依据。The turbidite sandbody lithologic trap developed in Dongying delta is a key exploration target in Es3 of the Shengli Oilfield. Oil reserves discovered in lithologic reservoirs are more than 10 million tons per year in recent years. Applying the theory and method of high resolution sequence stratigraphy, this paper has divided and correlated base-level circles on the basis of various delta base-level circle interfaces identified through well drilling and/or well logging as well as seismic data. The distribution of turbidite sand bodies and Dongying delta base-level circles are also discussed. All this provides scientific basis for further exploration of lithologic reservoirs.
