摘　　要：流动单元指标是流动单元的地质及油藏工程特征的综合参数，用它可以较为准确地描述储集层的非均质性。应用流动单元指标评价了宝北区块的储集层非均质性，认为宝北区块层内非均质性最强的是Ⅰ1、Ⅰ2、Ⅱ1小层，最弱的是Ⅲ1、Ⅱ2小层，层间非均质性最强的是Ⅱ油组，平面非均质性最强的是Ⅰ2、Ⅱ3小层，最弱的是Ⅲ1、Ⅱ1小层。： Flow unit is a block of reservoir rock， in which the depositional features and the percolation flow behavior are same or similar． The flow unit index is a kind of comprehensive parameter of geology and reservoir engineering． Using it the reservoir heterogeneity can be more accurately described． In this article， the flow unit index is applied to evaluate the reservoir heterogeneity in Baobei block． The results show that the strongest intrastratal heterogeneity is in Ⅰ1， Ⅰ2 and Ⅱ1 substratum， while the weakest intrastratal heterogeneity is in Ⅲ1 and Ⅱ2 substratum； the strongest interlayer heterogeneity is in Ⅱ oil reservoir； the strongest plane heterogeneity is in Ⅰ2 and Ⅱ3 substratum， while the weakest plane heterogeneity is in Ⅲ1 and Ⅱ1 substratum． Because these heterogeneity features occur， they must be appreciated adequately in development．
