| description | Natural low-permeability rock of granitic gneiss is excellent material for underground oil depot. Its microstructure and mineral composition are analyzed by SEM-EDS, the triaxial tests under different confining pressures are carried out. The evolution law of gas permeability with stress in the process of deformation and failure is discussed. The permeability property of granitic gneiss is different from that of the rock with large porosity, the curve of permeability with stress in the process of deformation and failure is relatively flat and no large fluctuations, but still reflects the compression, weakening and failure characteristics of rock samples, and the effect of confining pressure on the permeability is not very obvious due to its dense structure and small porosity. |
