摘　　要：凝析气藏渗流的主要特征是流体流动过程伴随着复杂的气液相变与近井地带的高速两相渗流。在分析凝析气藏高速多相渗流机理的基础上,模拟了考虑毛管数效应与非平衡流动影响的凝析液饱和度分布,并阐述了凝析气高速多相流动规律,为凝析气藏的生产动态分析与高效开发提供理论指导。It characters high-velocity two-phase flow near well when BHP is under the dew pressure with complex phase change. Based on analysis of high-velocity Multi-phase flow mechanism, the distribution of condensate saturation with Capillary Number and non-equilibrium flow is calculated by numerical simulation method. It is concluded of the law of high-velocity gas condensate flow to understand the producing performance of gas condensate reservoir.
