Abstract

Relative permeability is one of the main petroleum recovery controller that is a function of porous media and the reservoir fluid. Water flooding titled as one of the eldest EOR methods is still used in some of reservoirs. For proper perception and description of rheology in reservoir scale, knowing the flowing fluid processes specifications and mechanisms and also recognition of porous media type in pore-scale is necessary. In this way, the new age has arrived in reservoir study by introducing porosity model on glass. We can have the two-dimension porous media in actual size by designing a microfluidic chip. This article implies the effects of heterogeneity on relative permeability curves by micro model system and water flooding. High definition photos from different water and oil saturations and also Goodyear equations are used for analyzing the effects of heterogeneity on water and oil permeability in pore-scale. In conclusion, it is observed that in glass micro model oil and water relative permeability curves are dependent on porous media pores sizes. So that as much as these pores grows, the relative permeability will be increased. Moreover, pores sizes distribution and direction have effects on relative permeability.

渗吸过程中孔隙大小和孔隙分选对两相相对渗透率影响的研究
相对渗透率是控制原油采收率的主要因素之一,它是多孔介质和储层流体的函数。水驱作为最古老的提高采收率方法之一,至今仍在一些油藏中使用。为了正确认识和描述储层尺度下的流变学,必须了解流体的流动过程、特征和机理,并认识孔隙尺度下的多孔介质类型。至此,在玻璃上引入孔隙度模型,开启了储层研究的新时代。通过设计一种微流控芯片,可以得到实际尺寸的二维多孔介质。本文从微观模型系统和水驱两方面探讨了非均质性对相对渗透率曲线的影响。利用不同水、油饱和度的高清照片和固特异方程,分析了非均质性对孔隙尺度上水、油渗透率的影响。综上所述,在玻璃微观模型中,油水相对渗透率曲线与多孔介质孔隙大小有关。所以随着这些孔隙的增长,相对渗透率也会增加。孔隙的大小、分布和方向对相对渗透率也有影响。
