Abstract:
In the article of numerical modeling of non-isothermal filtration of natural gas through a single well in axisymmetric coordinates is carried out using the finite difference method. The mathematical model of natural gas uses the Latonov-Gurevich supercompressibility coefficient. Discretization of the mathematical model is carried out using linearized and implicit difference schemes on a quasi-uniform space-time grid. Results of numerical simulation are presented.
Keywords: filtration equation, supercompressibility coefficient, adiabatic expansion, Joule-Thomson effect, finite difference method, splitting method.
