Abstract

Abstract: The conversion among the components and related phase change plays an important role in the process of improving the recovery by gas injection, so it is very necessary to study the fluid flow law on reservoir fluids in the course of conversion and phase change. The paper developed a common numerical model on multiphase fluid flow by Darcy Law based on phase equilibri-um and Mass Conservation Law, and then the black oil model and the multi-component model for CO2injection were devel-oped. The model for CO2injection is different from the others for CO2injection which were not enough to consider the mass conservation when the CO2gas was dissolved in water.

Key words: multiphase flow, mathematical model, blackoil model, phase equilibrium, carbon dioxide injection, multi-component.
