Productivity formula of an infinite horizontal well array-an expansion of Muskat formula 水平井无限井排产能公式&Muskat公式的推广
When the mobility ratio is equal one, the sweep efficiency is 71% at the time of breaking of water flooding front. The error compared with the result of Muskat is only 1%. 计算得到当流度比为1时,水驱前缘突破时刻的波及系数为71%,与Muskat的实验结果误差仅为1%。
