摘要(Abstract)：

以探井、岩心及储层物性资料为基础,采用重矿物分析及砂地比分析方法,确定松辽盆地尚家—太平川地区泉三段物源方向;结合双物源控制分析砂体沉积相及沉积砂体类型,通过砂体精细解释及沉积背景分析,揭示不同砂体的平面展布特征,分析其演化规律并建立沉积模式。结果表明:尚家—太平川地区泉三段主要由南、北方向物源控制;研究区可识别曲流河相、三角洲相两种沉积相,其中三角洲相沉积最为发育;沉积砂体类型可细分为曲流河道、三角洲平原分支河道和三角洲前缘水下分支河道;砂体垂向分布受双物源控制,顺物源方向砂体连通性好,多期河道相互叠置,逆物源方向砂体呈透镜状发育,砂体横向分布存在"分段"特征。研究区泉三段由浅水三角洲平原逐渐向曲流河沉积转换,反映水体由深变浅的一次湖退沉积过程,为该区域油气勘探提供依据。
