The relation curves of water phase permeability of reservoir cores and back-pressure were obtained.
得到了裂缝性低渗透储层岩心水相渗透率随回压的变化曲线。
The flow resistance of foam is affected by those parameters such as surfactant concentration, oil saturation, temperature, permeability, water and gas phase velocity, etc.
泡沫的流动阻力受泡沫剂浓度、温度、油饱和度、渗透率以及水相和气相达西流速的影响。
So, after reservoir watering out as edge water and bottom water enters, the gas phase permeability will decrease greatly, and strong water lock effect will happen.
因此，当边水和底水进入储层发生水淹后，气相渗透率将极大降低，存在较强的水锁效应。
