| 摘 要： | 凝析气藏中的水汽对凝析气体系相态变化有影响。在地层中等温降压时，含水汽的烃类体系会发生反凝析现象。在反凝析现象中会产生凝析水和凝析油。这些反凝析液的聚集效应会造成凝析气井的产能严重损失。这就使得控制反凝析液的析出成为提高凝折气藏采收率的关键。在研究中，总结了含水汽凝析气体系的相态特征。同时，在对某含水汽凝析气体系相态实验分析的基础上，对该体系分考虑水汽和不考虑水汽2种情况进行相态仿真模拟。模拟结果大致与实验观测值一致。 |

| Abstract: | Water vapour in Gas condensate reservoir has an effect on the phase behavior of the Gas condensate system.Retrograde condensation will occur in the water vapour contained Gas condensate system when formation pressure declines at a constant tempeture.Condensate oil and condensate water will emerge in Retrograde condensation.Accumulation of Condensate liquid will produce serious loss of oil well productivity.Therefore,to avoid producing condensate liquid is the key measure to improve oil recovery.In Research to the water vapour contained Gas condensate system,we summarized the phase behavior of the Gas condensate system.At the same time,we conduct the simulation of the water vapour contained Gas condensate system under the two conditions:water vapour is considered or not,on the basis of experiment result analysis of some water vapour contained Gas condensate system.The simulation result is consistent with the experiment result analysis. |
