Abstract: A new solution method to compositional model is investigated,which is implicit to pressure and saturation of oil and gas,and explicit to mole fractions of components.The number of equations to be solved simultaneously is much less than that of the fully implicit method,but the stability is as good as such one.It is also shown that the present compositional software have good accuracy and exciting computation speed.

Key words: compositional model, software, gas condensate reservoirs, numerical simulation
