| 摘 要： | 基于油水两相渗流理论，建立了考虑含水影响的油水两相不稳定渗流试井分析的数学模型。在获得数学模型解后，作出了受含水率fw影响下新的油水井试井分析典型曲线。研究表明，在径向流阶段，压力导数表现为斜率值是(1-fw)／2的水平线，而单相流试井分析典型曲线是fw=0的特例。利用油水井新的试井分析典型曲线进行实例分析，论证了本文研究结果合理可行。

| Abstract: | Based on the water-oil phase flow theory, the paper has established the mathematics model of water-oil phase transient well test analysis containing water influence. After Mathematics model has been gained, the new typical curve on water-oil phase well test analysis influenced by water cut (fw) is worked out. Form investigation, pressure derivative is represented by a horizontal line which slope is (1-fw)/2 during radial flow,and typical curve on single-phase flow well test analysis is only a special example where fw is zero. By analyzing the examples using those, the result is reasonable and feasible. |
