This result showed that effective pressure was quite obvious when the liquid was moving in low permeating and porous medium.
以低渗透多孔介质为研究对象,通过实验得出渗透率随有效压力变化曲线。
Low permeating and porous medium was taken as an object for study, it can be educed from the experiment that the curve of permeability changed with the effective pressure.
在低渗透多孔介质中,由于孔隙半径小而不能忽略毛细管压力对油气体系相平衡的影响。
Since the pore radius is very tiny in the low permeability porous media, the capillary pressure should be taken into account.
这是因为低渗透多孔介质的孔隙很小,微小的孔隙度变化也会对渗透率产生较大的影响。
This was because the pore space of low permeating and porous medium was very small.
