摘要: 松辽盆地姚家组一段的葡萄花油层属于大型湖泊—三角洲沉积环境,具有下生上储式成藏组合特征,油藏主要分布在中央坳陷成熟烃源岩范围内,沿盆地长轴方向发育的北部水系大型三角洲复合体对油藏分布具有宏观控制作用;三角洲不同沉积相带控制了砂体类型及圈闭类型的分布,因此油藏类型平面上相应呈现分带性,可分为构造油藏带、复合油藏带及岩性油藏带;高成熟烃源岩控制油气藏主要分布在中央坳陷区;不整合面对油气成藏具有输导作用,油气藏集中发育在水进体系域储层中,而水退体系域主要发育水层。

Abstract: Putaohua oil layers of the First Member of Yaojia Formation in Songliao Basin are large lacustrine delta sediments, and they have the characteristics of lower generation and upper storage. Oil reservoirs are mainly distributed within the range of source rocks of the central depression. The large delta complex in the north developed along the long axis of the Basin macroscopically controls the reservoir distribution. Different sedimentary facies control the distribution of the types of sand body and traps, so reservoir types present zonality on the plane. Reservoirs could hence be classified into structural reservoir, complex reservoir and lithologic reservoir. Oil and gas reservoirs controlled by high mature source rocks control concentrate in the central depressions. Oil and gas reservoir formation could be transported through unconformable surface. Oil and gas reservoirs mainly developed in the Highstand Systems Tract, while aqueous layers mainly developed in the Regressive Systems Tract.

Key words: Songliao Basin, the First Member of Yaojia Formation, large lacustrine delta, reservoir distribution
