mid-low permeability

基本解释

And low permeability reservoir is slower than mid-high permeability reservoir in pressure wave propagating velocity.
低渗透油藏比中高渗透油藏的压力波传播速度慢。
Tazhong 16 of Tarim oil field as an example, a development method for the layer reservoir of mid -low permeability bottom water was introduced in the paper.
以塔里木油田的塔中16油田为例，介绍一种适合层状低渗边水油藏特点的开发模式。
The low permeability reservoirs is becoming more and more important, as well as the mid-high permeability old fields entered mid-high water cut stage with the development of oil gas exploration.
随着油气勘探程度的不断加深，以及以中、高渗透率为主的老油田逐渐进入中高含水期开采，低渗油藏的重要性日益明显。
