| 摘 要： | 井周地层应力状态对油井产量有重大的影响,将岩层视为均质的连续弹性体,用弹性力学的方法,分析了井边附近岩层应力分布状态,在此基础上考虑了应力与岩层渗透率的关系,研究了井周地层应力对于油井产量的影响。

| Abstract: | The stress state around underground layer has an important affect on the output of oil well.Considering rock layer as a homogeneous and continuous elastic body,the stress distribution state around well is analyzed by the method of elasticity.On the basis of this,the affect of stresses around well is researched according to the between stress and rock permeability. |

| Keywords: | permeability underground layer damage around well stress concentration |
