内容摘要:Mineral dissolution plays an important role in many subsurface transport processes including water-flooding, geological CO2 sequestration (GCS), and matrix acidizing in carbonate formations. Such a dissolution process could dramatically affect the efficiency of the oil/gas production. Hence a numerical model that accurately describes the dynamic behavior of fracture evolution is essential. In this talk, we introduce a 3-D mathematical model that combines the Stokes--Brinkman equation and reactive-transport equations to describe the coupled processes of fluid flow, solute transport, and chemical reactions in both single and multiple mineral systems. The proposed numerical model can be applied to describe 3-D linear flow and radial flow for different scenarios. We employ a numerical procedure based on the staggered-grid finite difference method and the control volume finite difference method. We will also introduce a multiscale hybrid-mixed method for discrete fracture models. The three-dimensional fluid flow in the reservoir and the two-dimensional flow in the discrete fractures are approximated using mixed finite elements. Several test cases illustrate the effectiveness of the proposed approach comparing with direct simulations.
