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。

Abstract

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 comprehensively. Also we can accurately predict the production performance of gas well at different times, improving the analysis result of numerical simulation.
