中文摘要：
目前国内外针对波动法强化采油的作用机理进行了部分研究，但波动条件下油滴的变化形式即运动规律并不明确。利用宏观和微观相结合的方法对波动法采油的作用机理进行研究，通过物理模拟实验对波动条件下水中油滴的变化进行了观测；在对斜壁上液滴进行受力分析的基础上，通过计算得出了液滴发生移动的临界平衡条件。分析认为，当波动作用打破该平衡条件时，液滴就会发生移动并被驱替流体携带。
英文摘要：
The dynamic mechanism of EOR by vibration method has been studied partly in recent years, but the droplet＇ s change due to vibration is not clear. Function mechanism of vibration on EOR is studied in both micro and macro respects. The change of oil drop in water under vibration is observed by experiment. Then all the forces acting on the droplet on inclined wall under the vibration is analyzed. On that basis, the critical equilibrium condition for the droplet to move is gotten, and it is concluded that when the vibration tip the balance, the droplet will move and then will be carried out the surface by the flooding fluid.
