基于Logistic模型的驱油效率与注入倍数关系定量表征方法
Quantitative Research of Relationship Between Oil Displacement Efficiency and Pore Volume Injection Ratio Based on Logistic Model
摘要
Abstract
Oil displacement efficiency is one of the important parameters affecting the oil reservoir recovery,and the pore volume injection rate is the decisive factor that directly affects the ultimate oil displacement efficiency in the sweep zone.The semi quantitative relationship between the displacement efficiency and the injection volume of pore volume is derived by using the percolation equation expressed by the phase permeability index,combining with the B-L theory and the Welge equation.The relation curve satisfies the life cycle theory and the quantitative relation expression between them is deduced according to the law of Logistic growth.At the same time,the optimal pore volume injection ratio is determined by the two-order derivative curve.With the oil field entering the high water cut stage,the quantitative evaluation method of oil displacement efficiency is of great significance for evaluating the development effect of water flooding reservoir and tap the potential of the reservoir.关键词
