摘　　要：在稳态条件下推导了考虑油、气、水三相流动区及油、气、水、硫四相相态变化影响的气井流入动态模型,建立了气井井筒动态预测模型、井筒携固模型、井筒携液模型。结合地层流入、井筒流出、井筒携液、井筒携固等模型,提出了更为综合、全面的气井生产动态预测方法,并进行了实例计算,结果表明,该方法能更好地进行考虑凝析水、元素硫多相流体复杂相态变化影响的气井生产系统敏感参数分析,指导该类气井实现最优化生产,具有理论和实际意义。Considering the phase behavior of multi-phase liquids, this paper developed a dynamic inflow model for the gas-well, and established a performance prediction model of condensate gas wells. In combination with the formation inflow model, wellbore outflow model, it has also drawn a system analysis curve. Through this curve, we can predict the gas well production performance more directly and compre-hensively. Also we can accurately predict the production performance of gas well at different times, improving the analysis result of numerical simulation.
