Thomas and Ward have shown that the measured permeability of many western gas sandstone cores is significantly decreased by increased test
confining pressure, whereas
effective porosity is only slightly affected. 来自:THE RELATIONSHIP OF PERMEABILITY TO CONFINING PRESSURE IN LOW PERMEABILITY ROCK

我说过了,微间隙对实验结果产生重要影响,夸大了应力敏感程度,这些都是实验假象,都不是岩心本身的性质,而是柔软的岩心封套的性质。
