NON-EQUILIBRIUM TRANSPORT OF A GAS-CONDENSATE MIXTURE IN A POROUS MEDIUM

The transport of a two-phase multicomponent gas-condensate mixture in the vicinity of a vertical production well is considered taking into account the possible non-equilibrium of the process, namely, the kinetics of gas-condensate phase transition. Results of numerical solution of the transport prob...

Description
Summary:The transport of a two-phase multicomponent gas-condensate mixture in the vicinity of a vertical production well is considered taking into account the possible non-equilibrium of the process, namely, the kinetics of gas-condensate phase transition. Results of numerical solution of the transport problem are presented for different well production rates and different rates of relaxation to the thermodynamic equilibrium of the reservoir mixture. It is shown that the effect of non-equilibrium increases with increasing well production rate.
