gas permeability constant

基本解釋

Permeability measurements on the samples of Da-Niu-Di gas reservoir are performed under the conditions of constant confining pressure and cycling fluid pressure.

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(shù)氣藏模擬計算中，都假定了孔隙度、滲透率蓡數(shù)保持常數(shù)，以致模擬計算結果比實際偏高。
