摘　　要：利用地质和地球物理资料,依据层序界面特征,将渤海海域古近系划分为1个一级层序、4个二级层序和14个三级层序。根据断裂形态、地层接触关系及剖面样式,建立了断裂陡坡带、缓坡断裂带、简单缓坡带、凹中隆起带和洼陷-轴向带等5种构造带的层序地层构成模式。Bsaed on informations of geology and geography, the Paleogene sequences including 1 first order sequence, 4 second-order sequences and 14 third-order sequences are recognized in the Bohai area. According to fracture shape, contact relations and section style of strata, 5 sequence stratigraphy and sedimentary system composition models are setted up including steep-slope zone. gentle structural slope zone, gentle slope zone, uplift and depression.
