Simulation of processes of filtration of hydrocarbons in a gas-condensate stratum

An experimental investigation is performed of the effect of formation and destruction of a condensate plug under conditions of filtration of a binary mixture of hydrocarbons (methane-$n$-butane) in a one-dimensional model of gas-condensate stratum. A mathematical model is developed which enables one to calculate the hydrodynamic and thermodynamic characteristics of the process of filtration of hydrocarbons in the stratum. Qualitative and quantitative agreement is obtained between the experimental results and calculated relationships.
