中文摘要:本文选择地层渗透系数受应力影响而变化作为研究流体运移的基础。压实固结和构造作用所产生应力对渗透系数影响的有限元数学模拟研究表明，平均有效应力与介质渗透性能呈负相关的变化趋势，应力驱动流体由应力高值区向应力低值区运移。

Variation of Permeability Coefficient of Strata under Different Stresses and Their Numerical Models for Their Influence on Fluid Migration

Abstract:The influence of stresses on permeability coefficient of strata is selected as the basis for the study on fluid migration . The numerical model for the influence of compaction and structural stresses on permeability coefficient shows that the average effective stresses have a negative correlation with permeability of media and that the fluid migrates from high stress area to low stress area by stress driving.
