摘　　要：针对喇嘛甸油田特高含水期水驱精细调整需求,采用了高分辨率层序地层学原理与层次界面分析原理的储层沉积界面划分方法,研究河流—三角洲沉积背景下的单期河道单元沉积界面识别、划分与对比方法。提出井点砂体沉积微相以测井相图版为识别标准,依据沉积模式基本规律及演化规律研究各类砂体的平面分布特征。大大提高了井间各类砂体的识别精度,形成了高分辨率层序地层学原理指导下的河流—三角洲相储层沉积微相识别技术,有效指导特高含水期水驱精细调整,确保该区块在特高含水期含水不升、产量不降的高效开发效果。According to fine adjustment demand of water flooding in high-water cut stage of Lamadian oilfield,using high-resolution sequence stratigraphy principle and hierarchical interface analysis principle,this paper discusses the identification,division and comparision of single phase unit river depositional interface.In this paper,the depict distribution characteristics method of sand body based on basic rule of sedimentary pattern and evolution is presented,and logging phase diagram is used as recognition criteria of well point sand body sedimentary microfacies,also characteristic of seismic lithologic and inversion result is referenced on interwell.The research conclusion can greatly improve identification accuracy of variety of sand body on interwell,and technology for identifying sedimentary microfacies on fluvial-delta facies reservoir based on the high-resolution sequence stratigraphy is formed,the research conclusion can effectively guide fine adjustment of water flooding in high-water cut stage and make sure this block has high-efficiency development effect of no risen water content and no reduce production.
