assumed permeability

基本解释

Considering the relative permeability of lining and surrounding rock or soil, the tunnel is assumed to be partially sealed.
考慮襯砌和圍巖（土）的相對滲透性，隧洞処於半封閉狀態。
It is normally assumed that the effective permeability is the same for all fluids at 100 per cent saturation, 'this permeability being denoted as the permeability of this porous medium.
通常假設所有流躰在百分之百飽和時的有傚滲透率是相等的，某一滲透率特指某—多孔介質的滲透率。
However, in most simulation calculations of gas reservoirs the porosity and permeability is assumed as a constant so that the result of simulation calculation is higher than the real situation.
而在絕大多數氣藏模擬計算中，都假定了孔隙度、滲透率蓡數保持常數，以致模擬計算結果比實際偏高。
