Technique of numerical simulation of wave processes in a heterogeneous hydrate-containing porous medium

Abstract

A technique for numerical simulation of wave propagation in a hydrate-containing porous medium consisting of layers with different properties is proposed. The method is based on a mathematical model previously developed by the authors, which considers the difference between the velocities and pressures of the skeleton and fluid, and the McCormack finite difference method. A computer implementation of the model was performed, and preliminary calculations were carried out, which showed the efficiency of the proposed methodology. The possibility of applying this approach to the numerical solution of the problem of propagation and reflection of pressure waves in a layered hydrate-containing porous medium is shown.
