摘要： 在建立岩相-电相-沉积相图版基础上,将高尚堡油田沙河街组三段二、三亚段扇三角洲砂体划分为9类自然伽马曲线形态与组合(M),8类岩石类型(N),构成M/N形式的测井相,以表征不同类型的砂体。并利用两口井的地层倾角测井资料,通过短对比矢量图的对比,区分出显示大红模式的河道砂体,大蓝模式的砂坝型砂体和低角度小蓝小绿模式的远端席状砂体。确定古水流NNE和NW,砂体延伸方向和古水流方向一致,由NNE向SW或由NW向SE延伸,砂体加厚方向为SEE和SW,沉积时水深不超过15m.

Abstract: Based on the plate of lithofacies, log factes and sedimentary factes, the fan-delta of the third member of the Shahejie Formation in Gaoshangpu oil field could be divided into 9 natural gamma curve shapes and assemblages (M), 8 rock types (N). This constitutes M/N type of log factes so as to demonstrate different kinds of sand bodies. The dipmeter data from two wells were used to distinguish channel sand body represented by large red mode, sand bar represented by large blue mode and distal sheet sand body of small blue or green mode through arrow plot of short correlation. The results sho that the stretch directions of sand bodies are coincident with that of paleocurrent,the water depth was less than 15 m during deposition.
