Estimating equivalent permeability at grid block scale of numerical models is a critical issue for large-scale fractured porous rocks.
However, it is difficult to constrain the permeability distributions for equivalent fracture models as these are strongly influenced by complex fracture properties.
This study quantitatively investigated equivalent permeability distributions for fractured porous rocks, considering the impact of the correlated fracture aperture and length model.
Two-dimensional discrete fracture models are generated with varied correlation exponent ranges from 0.5 to 1, which indicates different geomechanical properties of fractured porous rock.
The equivalent fracture models are built by the multiple boundary upscaling method.
Results indicate that the spatial distribution of equivalent permeability varied with the correlation exponent.
When the minimum fracture length and the number of fractures increase, the process that the diagonal equivalent permeability tensor components change from a power law like to a lognormal like and to a normal-like distribution slows down as the correlation exponent increases.
The average dimensionless equivalent permeability for the equivalent fracture models is well described by an exponential relationship with the correlation exponent.
A power law model is built between the equivalent permeability of equivalent fracture models and fracture density of discrete fracture models for the correlated aperture-length models.
The results demonstrate that both the fracture density and length-aperture model influence the equivalent permeability of equivalent fracture models interactively.
