摘要: 渤海湾盆地A油田新近系明下段Ⅱ—Ⅴ油组是其主力含油层位。通过观察分析岩心资料的沉积构造特征、岩矿特征和粒度特征、测井形态、地球物理属性等特征,综合判定其主要发育曲流河和浅水三角洲两种沉积相类型,油田范围内曲流河主要发育河道、决口扇、天然堤和泛滥平原4种沉积微相,浅水三角洲主要发育水下分支河道、水下天然堤、河口坝和分流间湾4种沉积微相。通过分析沉积相特征,结合高分辨率层序地层学观点,对A油田明下Ⅱ—Ⅴ油组的垂向演化特征进行了探讨,结果表明:处于长周期上升半旋回的Ⅴ油组曲流河呈条带状分布;处于长周期下降半旋回初期的Ⅳ油组浅水三角洲平面呈坨状,内部砂体连通性差;处于长周期下降半旋回中期的Ⅲ油组浅水三角洲平面呈朵叶状,砂体以侧向叠置为主;处于长周期下降半旋回晚期的Ⅱ油组浅水三角洲平面呈鸟足状,砂体以垂向叠置为主。最终提出该油田沉积演化模式。

Abstract: Ⅱ-Ⅴ oil groups are the main oil layers in the lower part of Minghuazhen Formation(N1mL) in Oilfiled A, Bohai. By observation and analysis of the characteristics of sedimentological structure, rock and ore, particle size in core, well logging types, geophysical attributes characteristics,the sedimentary environments mainly include meandering river and shallow water delta. The meandering river mainly develops 4 kinds of sedimentary microfacies, which are channel, splay, natural levee and flood plain. But the shallow water delta mainly develops 4 kinds of sedimentary microfacies, which are underwater distributary channel, the underwater natural levee, the mouth bar and interdistributary in oil field range. Through the analysis of the characteristics of sedimentary facies, combined with high resolution sequence stratigraphy, and discussed the vertical evolution characteristics of Ⅱ-Ⅴ oil groups in the lower part of N1mL in Oilfiled A, Bohai, we find that meandering river of Ⅴoil group in a long period of ascending half cycle has the characteristic of strip distribution, and shallow water delta distributes a lump taye in the plane, and the internal sandbody has a poor connection, which is developed in Ⅳ oil group in the early stage of a long period of descending half cycle. The shallow water delta distributes a lobate taye in the plane, sand lateral stack, which is developed in Ⅲ oil group in the middle stage of a long period of descending half cycle. The shallow water delta distributes a bird-foot taye in the plane, sand vertical stack, which is developed inⅡoil group in the last stage of a long period of descending half cycle. Finally, it puts forward the model of sedimentary evolution of the oil field.

Key words: Bohai oilfiled, N1mL, Meandering River, shallow water delta, sedimentary evolution model
