| Abstract: | The low-ultralow permeability measurement is one of the most important research topics in fluid mechanics and rock physics.Quantification of fluid transport through fault zones is critical for the understanding of fault mechanics and prediction of subsurface fluid flow.In order to obtain the information about the fluid-flow processes in seismogenic regions,we have designed and constructed a distilled water/gas-medium permeability measurement apparatus capable of achieving ultralow permeability.The new measu... |
