Summary:A reliable prediction of phase behavior is important in the development of gas condensate field. Critical properties of C7+ have great impaction on phase behavior. Improved genetic algorithm used in calculating C7+ critical properties is proposed. Used this method, optimum matching between critical temperature and critical pressure is seek. And then, phase equilibria are calculated using PR equation of state. The result is compared with constant volume depletion test and Eclipse software result.
