摘要
利用人工振动技术增加石油产量的机理之一是地层的机械共振作用。提出了一种简化的地层模型，并将其转化为一个双自由度有阻尼振动系统。研究了各种不同厚度的地层的振幅与振动频率的关系、共振频率与固有频率的关系以及品质因素 Ｑ 对地层振幅和共振频率的影响，得出有意义的结论。
We consider that mechanical resonance is the one cause of enhanced oil-recovery. We bring forward a simplified model of layers and convert this model into a vibration system of two free-dimentions with damp. We have studied the relationship of vibration amplitude of layers at a varities of thickness and vibrating frequency, the relationship of resonance frequency and inherent frequency, and the effect of quality factor Q on vibration amplitude and resonance frequency. Some significative conclusions have been got.
