摘　　要：宝北区块Ⅲ1厚油层非均质严重,剩余油分布复杂。通过对厚油层细分流动单元研究,将储层划分为彼此相对独立的A、B、C、D、E等5类流动单元,利用流动单元控制建模技术,建立精细地质模型。并利用数值模拟技术,对该区的生产历史进行了拟合,结合动态分析方法研究了不同流动单元剩余油分布规律,为厚油层注水开发调整提供了依据。Heterogeneity in thick oil reservoirs of Baobei Block Ⅲ1 was serious and residual oil distribution was complex.Through subdivision of flow units of reservoirs,the Ⅲ1 reservoir in Block Baobei is classified into 5 kinds of separate flow units:A,B,C,D and E.Based on these flow units,a fine geologic model is established;anumerical simulation technique is used to match the production history of the reservoir Ⅲ1,in combination with dynamic analysis,the distribution law of residual oil in different flow units is studied,and it provides a guidance for waterflooding adjustment of thick oil reservoirs.
