摘　　要：应用高分辨率三维地震资料,对黄骅坳陷中区岐北凹陷东营组进行地震地层学分析,通过该区地震反射终止类型、地震相等的研究,识别三级层序界面,并将东营组划分为四个(SQEd1s、SQEd1x、SQEd2、SQEd3)三级层序,并总结出歧北凹陷东营组的缓坡破折型和断裂陡坡型两种层序构成样式。On the basis of high resolution 3D seismic data,analyse the seismic stratigraphy in Dongying formation, Qibei sag in central Huanghua Depression. The Dongying formation can be divided into 4 third-order sequences （SQEdls, SQEdlx,QEd2, SQEd3） though the identification of types of seismic reflection , seismic facies and sequence boundaries. Two typical tectonic backgrounds developed in the study area： Gentle slope characterized by slope--break and Fault-controlled steep slope.
