【 摘 要 】

Theory of self-oscillations in the filtration of gas-liquid mixtures in a porous media is presented. Self-oscillatory mode of filtration of hydrocarbon mixtures has described. The possibility of occurrence of similar modes without phase equilibrium (the effect of "gas bearing") is discussing. System of filtration equations, including energy equation, is also explored is able to reveal such effect in filtration of geothermal waters.
