The effective permeability is stated as some numerical value at some given saturate conditions 有效渗透率用在一定饱和条件下的数值表示。
Effective permeability is introduced here to describe the simultaneous flow of more than one fluid 有效渗透率描述多种流体同时流动的情况。
Effective permeability are normally measured directly in the laboratory on small core samples 有效渗透率一般是在实验室中对小体积岩芯样品直接测量得出的。
The saturations , if know , should be specified to define completely the conditions at which a given effective permeability exist 如果已知饱和度,就应将其详细说明来定义特定有效渗透率的存在条件。
It becomes necessary , therefore , to specify the fluid saturation when stating the effective permeability of any particular fluid in a given medium 当陈述特定介质中任何一种流体的有效渗透率时,有必要说明流体的饱和度。
In the definition of effective permeability each fluid phase is considered to be completely independent of the other fluids in the flow in the network 在有效渗透率的定义中,每一个流体相被认为与流体网络的其它流体相互独立。
This definition of effective permeability implies that the medium can have a distinct and measurable conductance to each phase present in the medium 这一有效渗透率定义意味着介质对存在于其中的每一种流体有明显的和可测量的传导性。
Unlike the previously defined permeability , many values of effective permeability now exist , one for each particular condition of fluid saturation 与上文所定义的渗透率不同,渗透率有很多数值,每一个数值都表示流体饱和的特定条件。
The effective permeability is a relative measure of the conductance of the porous medium for one fluid phase when the medium is saturated with more than on fluid 有效渗透率是在多孔介质被多种流体饱和时,对单一流体相孔隙介质传导性的相对度量。
It is normally assumed that the effective permeability is the same for all fluids at 100 saturations , this permeability being denoted as the permeability of this porous medium 通常假设所有流体在百分之百饱和时的有效渗透率是相等的,某一渗透率特指某一多孔介质的渗透率。
