摘要
Mobility of each phase in multi-phase fluid flow in porous media is defined as the ratio of effective permeability to viscosity of specific phase. The question is how to define the mobility of a multi-phase fluid system considered as one phase. It is significant to define such a parameter. It is known that oil production is not directly proportional to permeability. Is it possible to define a parameter which is directly proportional to oil production or production performance? To this end, the concept of global mobility in the case of two-phase fluid flow was proposed in mis article to characterize the mobility of a two-phase fluid system considered as one fluid. The production rate at a specific oil recovery was also proposed to represent the production performance. It was found that the production performance was directly proportional to the global mobility based on the experimental data from rock/oil/water systems with different permeability and different interfacial tension. The concept of global mobility may also be applied to quantify the two-phase fluid flow property in porous media and to conduct formation evaluation in petroleum industry as a new parameter. 水相俘获伤害倾向在紧气藏 每一阶段的多相流动在多孔介质中流体的比率是定义为有效渗透率的特定阶段对粘度。现在的问题是如何定义的机动性多相流体系统视为一个阶段。这是很重要的,来定义这样一个参数。众所周知,原油产量不直接成正比。它是可能的定义参量正比于石油产量和生产性能?为了达到这一目的,全球流动性的概念的提出了两相流体的流动的信息管理系统(mis)条的两相流体系统视为一个流体。
