摘    要:洪积扇砂砾岩储层岩石类型复杂多样,不同岩石相的含油性、渗流性能及油水运动存在差异,以此可以寻找砂砾岩油藏开发后期的剩余油.研究表明:通过野外考察和岩心观察及FMI测井分析,砂砾岩储层可以划分出7种类型的岩石相,其中片流成因的交错层理—细砾岩相和平行层理砂岩相大孔粗喉,饱含油,渗流性能最佳,注水开发快速水进;杂基颗粒支撑...

关 键 词:洪积扇  砂砾岩  岩石相  渗流机制  开发特征  剩余油分布

Abstract:The remaining oil in the conglomerate reservoir can be prospected and recovered based on the diversity of alluvial fan rock types of the reservoir and oiliness and fluidity and oil-water movement of different lithofacies.The field observation,core analysis and FMI logging of the conglomerate reservoir show that this reservoir consists of 7 types of lithofacies.The study result shows that the cross bedding-fine conglomerate and parallel-bedding sandstone is the best in porosity,oil saturation and fluidity,gr...
Keywords:alluvial  conglomerate  lithofacies  flow mechanism  waterflooding characteristic  remaining oil distribution
