摘要
应用层序地层学研究了东部某油田HJ凹陷目标区层序的划分、结构及形成发育史 ,预测了该区隐蔽油气藏的分布 .结果表明 :HJ凹陷目标组可划分为SⅢ5,SⅢ6 ,SⅢ73个层序和 7个体系域 ;该组储层砂体类型以扇三角洲分流河道及盆底扇浊积砂体为主 ,砂、泥层相互叠置 ;隐蔽圈闭发育层位以SⅢ6 低位体系域最优 ,SⅢ7低位体系域和SⅢ5高位体系域次之 ;最有利的隐蔽油气藏分布带为西斜坡临近三河次凹的内斜坡北段 。
Stratigraphy is the effective means to predict oil and gas reservoir. This paper establishes the target group high-resolution sequence layer structure by analyzing target area high-resolution sequence and studying earthquake data stratigraphy, predicts and evaluates the hidden oil and gas reservoir of HJ concavity, by applying principles of high-accuracy stratigraphy and taking into consideration the forming condition of enclosure and the forming controlling factors of the hidden oil and gas reservoir.
