结合岩石力学、粘性流体动力学以及流固耦合力学的理论,研究得到了一种分析振动采油中地层饱和多孔介质波动规律的新方法。该方法以流体和固体的波动方程为基础,考虑流固两相间相互作用的粘滞阻力和惯性阻力的耦合效应,得到了一种描述振动采油中地层饱和多孔介质波动规律的实用模型,并用近场波动数值模拟理论求解。该方法物理意义明确,理论可靠,实用性强。

Vibration stimulating recovery technology lacks a whole theory system, which makes a very large blindness in production at present. According to rock mechanics, viscous dynamic mechanics and fluid-solid coupled mechanics, the paper obtains a new method of analysis on the law of vibration wave propagating through saturated porous media in vibration production. The method is based on the fluid wave equations and solid wave equations, considers the viscous force between fluid and solid and establishes a practical model of vibration wave propagating through saturated porous media. The model is also solved by near-field wave simulation theory. The physical meaning of the model is cleared and definite, the theory is reliable.
