Characterization of Fractured Reservoir and Anisotropy Parameters Calculation of Permeability Tensor

Abstract:

Fracture as the main seepage channels influence the deployment of well patterns and development effects in many kinds of reservoirs because of its strong permeability anisotropy. In this paper, we describe the fracture characterization of fractured reservoir with geometry parameters and establish the analytical models of full anisotropic permeability tensor by using the parallel plate model and tensor theory. Research shows that fracture aperture and density are the mainly two factors that have big impacts on equivalent fracture permeability and its anisotropy. The changes of fracture aperture, fracture density, fracture opening or closure not only alter the magnitude of fracture permeability, but also change the directions of the principal permeability of fractures.
