Abstract: According to the characters of fluvial and delta reservoirs in the Shengli Oil Field,two kinds of flow units in this oilfield were divided into four types respectively in consideration of lithology,physical property,microscope characters,sedimentary facies,and other dynamic factors.The flow unit modes of fluvial and delta reservoirs were developed according to the features of the flow units.The flow unit E has the best physical character,and the flow units G and M are the best reservoirs,while the physical character of the flow unit P is the worst. The distribution law of remaining oil in flow units was extrapolated. The distribution laws of remaining oil in different flow units are various.The flow unit E is more easily to be water-flooded.The remaining oil was enriched in the flow units G and M.The flow unit P has no development value due to its bad physical characters.Remaining oil is always enriched in the conjunction of flow units and near inter-bed. For fluvial reservoir,the remaining oil is always enriched in upper layer while it is enriched in down layer for delta reservoir. The similar type of flow units in different sedimentary systems has the different distribution laws for remaining oil.The remaining oil in the delta reservoir is more homogenous than that in fluvial reservoir.The micro pattern of remaining oil has five types.

Key words: reservoir flow unit, remaining oil distribution, fluvial reservoir, delta reservoir, Shengli Oil Field

摘要： 依据胜利油区河流和三角洲储层的岩性、物性、微观特征、渗流参数和动态信息,分别将该油区两种储层流动单元分为4类,建立了河流和三角洲流动单元模式.其中,流动单元E的储层物性最好,流动单元G、M为最佳储层和产层,流动单元P的物性最差.在特高含水期,流动单元G、M内剩余油相对富集,宏观剩余油多富集在流动单元接合部位、隔夹层处;对于河流相储层剩余油多在韵律层上部富集;对于三角洲相储层多在韵律层下部富集.微观剩余油形式多样,有孤滴、薄膜、网状、斑状和连片状等5种类型.
