mid-low permeability

基本解释

And low permeability reservoir is slower than mid-high permeability reservoir in pressure wave propagating velocity.
低滲透油藏比中高滲透油藏的壓力波傳播速度慢。
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.
以塔裡木油田的塔中16油田爲例，介紹一種適郃層狀低滲邊水油藏特點的開發模式。
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.
隨著油氣勘探程度的不斷加深，以及以中、高滲透率爲主的老油田逐漸進入中高含水期開採，低滲油藏的重要性日益明顯。
