凝析气储量在世界范围内占很大的比例。对凝析气藏开发动态和经济效应的正确预测需要正确模拟这类气藏的流态和相态。近井地带的凝析油沉积会产生诸如近井带渗透率污染和目标凝析油位置不确定等开发问题。另外，随着开发时间的延长采出的气体越采越轻，其经济价值也越采越低。深入理解凝析油气的组成和凝析油气相对渗透军所表征的多相流动变化可以帮助解决这些问题。进而可以将恰当的相渗曲线应用于油藏模拟器中以优化气田开发。
Condensate gas reserves account for a large proportion of the world. Correct prediction of the developmental and economic effects of condensate gas reservoirs requires correct modeling of the fluid and phase behavior of such gas reservoirs. Condensate deposits near the wellbore can cause development problems such as near-wellbore permeability contamination and uncertain target condensate location. In addition, with the development of time to extract the gas taken more lenient, its economic value is more and more low. A deep understanding of the composition of condensate hydrocarbons and the multiphase flow changes characterized by the Condensate Hydrocarbon Relative Permeability Army can help to solve these problems. In turn, the appropriate phase-permeability curve can be used in reservoir simulators to optimize gas field development.
