摘要： 从多孔介质孔隙分布特征与水驱油微观机理出发,针对具单峰对数正态分布特征的孔隙结构,给出了一种可以定量描述油水在原始状态下以及水驱过程中的微观分布及其变化的方法。算例结果表明,该方法可较真实地揭示出水驱油过程中波及系数与油水微观分布及其变化的关系,并可推广应用到具双峰甚至多峰分布特征的孔隙结构中。

Abstract: It is significant to study water-drive micro-mechanism and the distribution of residual oil in porous media for enhancing water drive efficiency. Based on an understanding of pore distribution characteristic and water-drive micro-mechanism in porous medium, in view of pore structure with single-peak logarithm normal distribution, a method for quantitative description of oil-water micro-distribution under initial condition and water-drive process is proposed in this paper. The calculation result shows that this method can directly reflect the relationship between sweep efficiency and oil-water micro-distribution during water drive process, and can be applied to analysis of pore structure with binormal and multi-peak distribution.

Key words: water drive, pore, distribution, probability, sweep efficiency
