摘　　要：研究了用水平井开发底水油藏时出现的问题 ,结果表明 :当井位一定时 ,水脊高度明显受无因次流量影响 ,在水平井的正下方水脊上升得最高 ;当无因次井位为 0 .7时 ,无因次流量为最大值 ,说明该井位为最佳井位 .给出了见水时间预测公式 ,实例应用结果表明 。In this paper, we deal with the problem of developing water\|bottom reservoir by use of horizontal wells. The results show that the height of water crest is the function of dimensionless flow rate. The maximum height of water crest is at the position blow the well bore. When dimensionless location of well bore is 0.7, then dimension flow rate will reach the maximum value, and the location is called optimum location. Then the theoretical equation is given to predicate the water breakthrough time and an example is illustrated. The water breakthrough time predicated with the example is consistent with the actual data.
