In the present article, in an analysis of the results of an investigation of gas-condensate wells by the method of steady-state samples, use is made of known solutions to the problem of the steady-state filtration of a stratified liquid (gas) with constant properties [1, 2]. However, the filtration of a gas-condensate mixture to a well with the reduction of the pressure below the pressure of the start of condensation p+ is accompanied by considerable changes in the composition and properties of the gas and liquid phases which, in turn, have an effect on the filtration characteristics of a porous medium. Among the many communications devoted to this problem (see, for example, the reviews [3, 4]), there are investigations which take account of the effect of a change in the composition and properties of the phases on the characteristics of steady-state filtration [5–7]. Here, it is proposed to model real gas-condensate mixtures by pseudobinary or pseudoternary systems with experimentally determined phase ratios. However, there are still no sufficiently well-justified examples of the reduction of multicomponent mixtures to the above-mentioned model systems. The present article, within the framework of the theory of the filtration of multicomponent systems, discusses the problem of the steady-state filtration of a real gas-condensate mixture to a central well in a round stratum. |
