摘　　要：从构造坡折带层序边界在层序发育中的沉积学、地史学和石油地质学意义出发,通过分析层序界面上下的隐蔽圈闭的发育机理,探讨了隐蔽油气藏的沉积的动力学条件;通过解剖层序边界上下的隐蔽油气藏的内部结构,从储层流动单元层次上研究了油藏内部的油水层分布规律,得出‘在构造坡折带高分辨率层序地层边界是有利的隐蔽油气聚集带’这一结论。Beginning with the significance of sequence bound-ary in structural slop break zone in respects of sedimen-tology,geohistory and petroleum geology,this paper stud-ies the kinetic depositional conditions of subtle reservoirs though analyzing the development mechanism of subtle reservoirs above and below the sequence boundary.The distribution pattern of oil and water layers in the reser-voirs are researched at fluid flow unit level through ana-lyzing the interior structure of subtle reservoirs above and below the sequence boundary.It is concluded that high-resolution sequence boundary in structural slope break zone is a favorable hydrocarbon accumulation zone.
