流动单元研究是深化和发展油藏表征的关键，对揭示剩余油分布规律等具有重要的理论意义和实用价值。 在建立河流相及三角洲相流动单元类型划分标准以及判别式的基础上，对塔河油田 1 区三叠系油藏的储层流动单元进行了划分，研究了流动单元的空间分布特征，并分析了流动单元与储层构型及剩余油的关系。 结果表明，塔河油田 1 区三叠系储层流动单元可划分为 E（极好）、G（好）、M（中等）和 P（较差） 4 种类型，其中 E 型和 G 型流动单元分布面积较大，M 型和 P 型流动单元分布面积较小，同时流动单元的层间差异和井间差异明显。 E 型流动单元与横向砂坝分布范围一致，G 型流动单元与河道沉积及纵向砂坝分布相对应，表明储层构型与流动单元之间具有良好的对应关系。 E 型和 G 型流动单元剩余油较富集，是剩余油挖潜的主要方向，M 型流动单元是剩余油挖潜的次要方向，P 型流动单元剩余油地质储量有限，挖潜潜力较小。

The research of flow units is the key of deepening and developing reservoir characterization, and it has important theoretical intention and practical value on revealing distribution of remaining oil. Based on establishing classification standard and discriminant of flow units in fluvial and delta facies, this paper classified the reservoir flow units of Triassic in block-1 of Tahe Oilfield, and analyzed the spatial distribution of flow units and its relationship with reservoir architectural structure and remaining oil. The result shows that flow units of the study area can be classified into E（excellent）, G （good）, M（medium） and P（poor） types, while E and G types have the most extensive distribution, and M and P types have smaller distribution area. Meanwhile, the interlayer and interwell flow units have distinct discrepancy. The E type flow unit has consistent distribution with lateral sandbar, and G type flow unit is corresponding to channel deposit and lengthwise sandbar that are sand reservoir bodies with high porosity and permeability, which means that reservoir architecture has favorable correspondence with flow units. E and G types of flow units are the main digging orientation of remaining oil, while M type is the secondary digging orientation. P type of flow unit has limited geological reserves of remaining oil, therefore has less digging potential.
