深水浊积水道发育位置与形成过程复杂，目前国内外学者致力于其沉积机理和模式的研究。相对于陆上沉积，这些研究成果尚不能高效地运用到油气田开发中。因此，将构型模式与流动单元研究相结合的意义重大，表现为：①已有的构型级次的划分能够有效地指导流动单元渗流屏障和连通体的层次分析；②已有的沉积模式研究能够约束流动单元的分布规律；③二者的结合能将构型模式研究成果运用到油气田开发中。为此，以西非尼日尔三角洲深水浊积水道储层为例，在储层构型级次划分的基础上，分级次识别了渗流屏障和连通体；并运用多参数流动单元的划分方法，将储层划分为A，B，C，D 4类流动单元；最后，在构型模式的指导下进行了流动单元的单井解释及单一水道剖面与复合水道平面的流动单元分布特征研究，并以此指导油气田开发。研究表明：在单一水道级次，不同类型的单一水道内部流动单元发育类型和分布特征存在差异，流动单元的分布规律受控于不同单一水道类型的分布规律；在复合水道级次，水道体系不同时期水道迁移与叠置样式的差异，造就了流动单元平面分布特征的差异性。

The study of deep-water turbidite channels ( with their wired locations and complicated forming process ) has been mostly about their sedimentary mechanism and models .However ,the study results could not be effectively applied in actual development of oil and gas fields .We suggest that a combination of architecture model with flow units of the chan-nels be a better solution to the problem for the following reasons:①available architecture division of the channels can be used to guide directly and effectively a hierarchy analysis of seepage barriers and interconnected bodies of flow units in the channels;②existing sedimentary models can be resorted to constraint the distribution laws of the flow units ;and③a combination of①and②can be used to guide oil and gas development .We took a deep-water submarine fan reservoir of Niger delta in West Africa as an example to illustrate the idea .Based on available reservoir architecture division ,we iden-tified seepage barriers and interconnected bodies and divided the reservoir into 4 types(A,B,C and D) of flow units through multi-parameters-based flow unit identification .We then tried to interprete flow units of single well and study pro-file distribution characteristics of single channel and plain distribution characteristics of composite channels with the ar -chitecture model as a guidance .The results were finally applied to the development of oil and gas fields .The resarch shows that the types and distribution features of flow units of different single channels may vary greatly from one to ano -ther and the distribution of these flow units were controlled by the distribution pattern of different types of single channels . For composite channels ,the migration and stacking patterns of the channels systems at different stages led to a difference in flow unit distribution characteristics .
