Non-equilibrium effects in highly dissipative thermodynamic systems

The article is devoted to the development of the theory of nonequilibrium pressure and temperature fields in two-phase thermodynamic systems simulating natural oil and gas reservoirs. Such systems are classified as strongly dissipative, since the flow process is accompanied by the predominant action of internal friction forces. The studies carried out made it possible to significantly clarify the concept of thermodynamic processes and establish new physical laws governing the formation of temperature effects during fluid filtration in real porous media. It is shown that the maximum values of the temperature effect do not reach the value of the integral Joule - Thomson effect for any values of the parameters of the medium and liquid, and in real oil and gas reservoirs, temperature changes are several orders of magnitude smaller than those predicted on the basis of the equilibrium theory.
