摘　　要：低频振动采油技术已成为一项重要的物理增产、增注措施,但其理论研究水平目前还相对滞后于现场应用。针对这一问题,运用渗流力学、波场传播的基本原理,建立了低频波动条件下地层流体的渗流模型,定量描述了地层、流体参数与振动采油压力波动之间的关系,并利用解析方法分析计算,认为低频波场主要受储层渗透率和振动频率两大因素影响。振动采油现场施工可以通过适当调整振动频率改善施工效果。LF vibration oil recovery has become an important physical stimulation method, but its theoretical study is lagging behind field application. The basic theory of percolation mechanics and wave field propagation has been applied to establish a percolation model of formation fluids under LF fluctuation condition, quantitatively describe the relationship between formation fluid parameters and pressure fluctuation of vibration oil recovery, and calculate with analytical method. It is thought that LF wave field is mainly affected by reservoir permeability and vibration frequency. Field operation of vibration oil recovery can be improved by properly adjust vibration frequency.
