water displacement efficiency

基本解释

The oil recovery under water drive is an important factor for the evaluation of water displacement efficiency of a reservoir.
油藏水驱开发潜力是分析评价油藏开发开采水平的重要参数。
The oil-water displacement efficiency is the function of displacement pressure gradient and furthermore increases with the rise of well spacing density.
水驱油效率是驱替压力梯度的函数，随井网密度的增大而增大；
