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。
In general, these curves are characterized by high irreducible water saturation, low remaining oil saturation with high relative permeability and wider two-phase region.
一般相对渗透率曲线具有束缚水饱和度较高、残余油饱和度较低以及残余油状态相对渗透率较高、两相流动区间较宽的特点；
The results reveal that the initial water cut of low saturation sandstone reservoirs may experience a stable fluctuating phase, which is determined by initial oil saturation, and ca.
特低渗油藏的生产井初始含水率要比中高渗油藏的高，而且生产井开井生产后含水率有一段时间的下降。
