3D model and numerical algorithm for gas filtration in porous media

The article presents a three-dimensional mathematical model of the gas filtration process in porous media and numerical algorithm for solving initial-boundary value problem. developed is described using nonlinear differential equation partial derivatives with appropriate initial boundary conditions. proposed apparatus makes it possible to carry out hydrodynamic calculations taking into account changes main factors affecting under consideration: permeability, porosity, thickness layers, recovery coefficient, viscosity, etc. Computer implementation provides an opportunity solve practical problems analysis forecasting production various conditions impact on productive reservoir, as well making decisions development existing design new fields.
