摘要
Abstract
Continuation ( or Homotopy) method was applied to calculate thedew-point pressures of four gas condensate systems under reservoir temperatures in comparing with Newton iterative method and Broyden method. The effects of initial iteration pressures on the convergence of dew-point pressures were studied based on the results from the three different methods. The Peng and Robinson equation of state was used for all calculations. The results showed that continuation method is an efficient algorithm for the phase equilibrium calculations of reservoir fluids.关键词
