1) waterflood permeability
水驱渗透率
2) effective flooding permeability
有效驱动渗透率
1.
Practice in production of ultra-low permeability reservoirs indicate that it is difficult to evaluate the reservoir production performance with conventional development index effectively,so,the effective flooding permeability is introduced,and research shows the fluid can flow in the sublayers whose permeability is greater than the limit.
针对特低渗油藏生产采用常规开发指标难以有效评价油藏生产动态的问题,引入有效驱动渗透率的概念,认为只有渗透率大于有效驱动渗透率的油层中的流体才参与流动。
3) water phase permeability
水相渗透率
1.
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。
2.
The coal core flow tests are conducted in following steps: injecting 5 g/L salt water to measure water phase permeability,K_w;injecting in opposite direction N_2 gas to measure gas phase permeability,K_g,changing with time,t;injecting 2 g/L surfactant solution in the salt water and measuring K′_w;injecting in opposite direction N_2 gas to measure K′_g,changing with t;the water phase .
煤岩心流动实验程序如下:注5 g/L盐水测水相渗透率Kw,反向通氮气0。
4) hydraulic permeation rate
水力渗透率
5) PWP
纯水渗透率
6) rate of water infiltration
水分渗透率

分子式：
CAS号：
性质：液体以层流状态通过粉粒物形成填充层时，其渗透性能是不同的。如以渗透率K表示此性能，则。V0为液体的表观速度，m/s; μ为液体的黏度，kgf·s/m2；△P为粉粒层两端压强差，kgf·s/m2；L为粉粒层厚度，m；△P/L为压强梯度。
