摘要(Abstract)：

在水平井开采含夹层底水油藏物理实验的基础上,观察水脊形态变化及水淹规律,抽象出带隔板底水油藏水平井的物理模型。将物理模型划分为3个区,以多孔介质渗流理论为基础,利用镜像反映法和势的叠加原理,建立任一时刻水脊高度的计算模型,并根据物理实验得到的油井见水时水质点的运动路径对油井的见水时间进行预测,对见水时间影响因素进行分析。结果表明:水脊上升速度随时间的变化逐渐减缓;在隔板边缘下方处及水平井井底附近,水脊上升速度随时间变化较其余位置快,并且水脊高度在平面上的变化幅度也较大;随着隔板半径的增大及隔板与井的垂直距离增加,见水时间明显延后;见水时间随着水平井产量的增加而缩短。计算的水脊高度变化规律与物理实验相互验证,见水时间与实际误差约为4.9%,可为该类油藏开发提供参考。
