| 摘 要： | 采用微观水驱油模型实验测得西峰油田庄19井区长82储层26块样品的渗透率、水驱前含油饱和度以及在不同注入倍数、不同注入压力下的剩余油饱和度和驱油效率,以此参数为基础,应用统计分析软件SPSS将样品划分为E类、G类和M类3类流动单元。结合试验动态观察和数据分析,不同流动单元类型有着不同的渗流通道、驱替方式、驱油效率以及压力对驱油效率的作用。 |
| 关 键 词： | 微观水驱油模型实验 流动单元 驱油效率 驱替压力 |

| Abstract: | Twenty six samples from Chang 82 reservoir in wellblock Zhuang-19 of Xifeng oilfield are tested by means of sandstone micro-model for water-oil displacement experiment for the collection of the parameters of their permeability,oil saturation before displacement,remaining oil saturation and displacement efficiency under the different waterflood time and pressure.Based on these parameters with the employment of statistic software SPSS,the authors divide the samples into three types of flow units E,G and M.With the facilitation of the dynamic observation of the experiment and data analysis,the authors demonstrate that different types of flow units have different flow path,displacement model,displacement efficiency and effect of press to displacement efficiency. |
| Keywords: | sandstone micro-model for water-oil displacement experiment flow units displacement efficiency displacement pressure |
