| Zusammenfassung: | The invention provides a fractured carbonate rock matrix and crack coupling action characterization method. The fractured carbonate rock matrix and crack coupling action characterization method comprises the steps that 1, a flat plate crack model with different crack open degrees is constructed; 2, the flat plate crack model with the different crack open degrees is applied to a CT scanning carbonate rock matrix digital rock core, and a fractured carbonate rock three-dimensional digital rock core is constructed; 3, the distribution of a seepage field of the three-dimensional digital rock core is simulated through the lattice Boltzmann method, and the permeability of a three-dimensional digital rock core model is calculated; and 4, the permeability coupling coefficient is introduced, the permeability result is analyzed, and the permeability coupling coefficient expression is determined. According to the fractured carbonate rock matrix and crack coupling action characterization method, the problem that the total |
