根据注入不同孔隙体积倍数汪入水时岩样渗透率的变化，评价了注入水的敏感性。
The sensitivity of the injection water is evaluated based on permeability changes of rock samples as water injected with different multiples of pore volume.
该实验是在各项异性的固结作用后保持差应力，使用孔隙水控制装置在体积不变的应变控制条件下将孔隙水注入。
In the test, after anisotropic consolidation, keeping the deviator stress, pore water is injected using pore water control apparatus under a constant volumetric strain controlled condition.
体积流过量试验结果显示，当注入150倍孔隙体积注入水时，因粘土膨胀，渗透率下降达28%。
The result from the testing by volume flow overrate demonstrates that when injected water as much as 150 fold of pore volume is used, permeability is reduced as much as 28% due to clay swelling.
