摘　　要：为揭示低频波动激励下饱和单相流体多孔介质渗流规律变化,从低频脉冲波作用于油层后对储层物性影响的微观动力学模型与规律出发,建立饱和单相渗流流体的多孔介质弹性波传播理论模型。通过对波动影响储层渗流的动力学模型与规律揭示方面进行分析,可为波动采油技术和施工参数优化提供理论指导。In order to reveal the change of percolation rule of saturated single-phase porous media under low-frequency wave excitation,a theoretical model of elastic wave propagation of saturated single-phase porous media was established based on the microscopic dynamic model and rule of the effect of low-frequency pulse wave on reservoir physical properties.Through the analysis of the dynamic model and regularity of the fluctuation affecting the reservoir percolation,it can provide theoretical guidance for the optimization of the fluctuation oil recovery technology and construction parameters.
