| 摘 要： | 相态变化对凝析油气体系在多孔介质中的流动有较大影响。根据相态分布特征，将凝析气井中从地层到井筒的径向渗流划分为三个区域：无凝析油析出的单相气区，凝析油析出但不流动的过渡区，近井地带凝析油气两相区。分别考虑三个区域的相态特征及过渡区和两相区中凝析油析出对流体流动的影响，建立了凝析气井的流入动态预测的改进模型。结果对比表明，本文考虑过渡区的方法比通常使用的二项式模型和不考虑过渡区的两区模型结果更加合理。 |

| Abstract: | Phase change with formation pressure decline has a significant effect on condensate gas and oil flowing.According to the phase character,a gas condensate well undergoing depletion consists of three regions: a region containing single phase reservoir gas,a region of condense buildup where only gas is flowing,an inner near-wellbore region where both gas and oil flow simultaneously.In this paper,the character of phase distribution and the effect of condensate buildup in transitional region are taken into account respectively,then a modified model of gas condensate well deliverability is developed.Compared with usual binomial model and two regions model,the result in this paper is more reasonable. |
| Keywords: | gas condensate well phase distribution oil condensate pseudopressure inflow performance |
