文章基于直线供给边缘附近一口生产井以恒定产量生产,径向流动,地层在水平方向均质同性,推导出边水在不同时刻的界面移动方程及其边水突破时间,并通过实例将其突破时间与底水的突破时间进行了分析比较。这对于一口生产井的产水分析和布井开采剩余油均具有一定的指导意义。

Based on the following assumptions: a well near the oil water contact with constant pressure and straight-line edge is produced with constant flow rate,the oil of the layer with homogeneity in horizontal direction is radial flowed,the paper derivate the equation of motion of edge water. The time of the breakthrough of edge water and that of bottom water are analyzed and compared with. These are important and positive meaning to instruct to analyzed producing water of a well and to drill infill wells to exploit remaining oil.
