摘要： 在束缚水饱和度下油驱油和残余油饱和度下水驱水的实验基础上,运用前人的低渗透油藏低速非达西判定方法,得到了束缚水饱和度下油驱和残余油饱和度下水驱低速非达西的临界雷诺数。研究表明,束缚水饱和度下油驱和残余油饱和度下水驱低速非达西的临界雷诺数不同,也就是说,驱替与被驱替介质不同,产生低速非达西的临界雷诺数不一样。分析了产生这一现象的原因,并通过实例给出了应用临界雷诺数计算出现低速非达西的临界渗流速度。

Abstract: Lots of experiments are made based on oil-oil displacement under irreducible water saturation and on water-water displacement under residual oil saturation. With low-velocity non-Darcy flow method for low permeability reservoir, the corresponding critical Reynolds numbers under these two situations are obtained. The study shows the different Reynolds numbers mean that the different critical Reynolds numbers of low-velocity non-Darcy flow under these two situations are resulted from different media for displacing and being displaced. Furthermore, this paper presents the detail reasons for them and the case study for calculation of the critical flow velocity under low-velocity non-Darcy flow by using these critical Reynolds numbers.

Key words: irreducible water, residual oil, saturation, non-Darcy flow, Reynolds number
