Calculation of Equivalent Permeability of Different Fracture Intersections in Fractured Porous Media
This paper reports a case study of calculation of equivalent permeability in Hot Dry Rock (HDR) system using an approach based on finite volume Computational Fluid Dynamics (CFD) method. In this case study, mass flow rates of water in two fractures crossing in a 300 mm x 300 mm two-dimensional (2D) block are predicted by CFD method for different pressure drops. The predicted mass flow rates are...
متن کاملStudy on Flow in Fractured Porous Media Using Pore-Fracture Network Modeling
Microscopic flow in fractured porous media is a typical problem for the exploitation of tight reservoirs. The rapid-flow in the fractured porous-media is of great significance to efficient and continuous oil/gas exploitation. The fractures are expected to enhance flow conductivity and mass transfer between matrix and fractures, and to improve oil displacement during water flooding. However, the...
متن کاملNumerical Calculation of Equivalent Permeability Tensor for Fractured Vuggy Porous Media Based on Homogenization Theory
Abstract. A numerical procedure for the evaluation of equivalent permeability tensor for fractured vuggy porous media is presented. At first we proposed a new conceptual model, i.e., discrete fracture-vug network model, to model the realistic fluid flow in fractured vuggy porous medium on fine scale. This new model consists of three systems: rock matrix system, fractures system, and vugs system...
متن کاملAbsolute Permeability Calculation by Direct Numerical Simulation in Porous Media
Simulating fluid flow at micro level is an ongoing problem. Simplified macroscopic flow models like Darcy’s law is unable to estimate fluid dynamic properties of porous media. The digital sample reconstruction by high resolution X-ray computed tomography scanning and fluid-dynamics simulation, together with the increasing power of super-computers, allow to carry out pore-scale simulations throu...
متن کاملUpscaling of Hydraulic Properties of Fractured Porous Media: Full Permeability Tensor and Continuum Scale Simulations
The simulation of flow and transport phenomena in fractured media is a challenging problem. Despite existing advances in computer capabilities, the fact that fractures can occur over a wide range of scales within porous media compromises the development of detailed flow simulations. Current discrete approaches are limited to systems that contain a small number of fractures. Alternatively, conti...
