The influence of mathematical model parameters on the dynamics of pressure and temperature fields at non-isothermal filtration of an imperfect gas is investigated in a numerical experiment. A nonlinear system of partial differential equations obtained from the energy and mass conservation laws and the Darcy law are used to describe the process, and physical and caloric equations of state are used as closing relations. The boundary conditions correspond to a given depression at the bottom hole. The effect of assumption on isothermality of the filtration process on the pressure field and on the total gas production is estimated. The size of the possible zone of hydrate formation in the well bottom hole is determined for typical gas fields of the Northeastern Russia.
Keywords: mathematical modeling, nonisothermal filtration, imperfect gas, gas hydrate.
