摘要
作者在文中利用粘弹性波动理论来定量研究了人工振动采油的机理 ,首次推导出弹性波引起流体和固体振动强弱之比与储层属性的关系。理论计算表明 ,人工振动采油的方法对低孔、低渗和高粘度储油层作用效果最好 ,而且频率越高 ,效果越佳。为进一步优选激振参数 ,提高原油采收率打下了坚实的理论基础。
The mechanisms of artificial buffeting exploring are studied by elasticity wave theory in the article. In the first time, the correlation of the buffeting strength ratio of the fluid to the solid and reservoir elements are estimated. The theory computation shows that the method of the artificial buffeting exploring oil is especially efficient for low porosity? low permeability and high viscosity oil beds, and is also better for lower frequency wave. They lay an important theory foundation for selecting buffeting parameters and improving oil recovery.
