"Modern Problems of Applied Mathematics and Mechanics: Theory, Experiment and Applications", devoted to the 90th anniversary of professor Nikolai N. Yanenko

## Rozhin I.I.## The computational experiment in the problems of gas productionIn the computational experiment the influence of mathematical model parameters on the dynamics of pressure and temperature fields at non-isothermal gas filtration is investigated. To describe the process the authors use the non-linear system of partial differential equations, obtained from the energy and mass conservation laws and Darcy law. The physical and caloric equations are used as closing relations. Boundary conditions correspond to gas extraction at a given pressure drop at the bottom hole. It has been shown that the influence of temperature field on such integral characteristics as cumulative gas production is the most considerable at moderate pressure drops. The example is given which shows that the zone of possible hydrate formation in the gas reservoir is of a very small dimension.
