| 摘 要： | 凝析气藏随着压力、温度等热动力学条件的改变,凝析油气体系的组成及其物性参数也发生变化,发生相间传质和相态变化等物理化学现象,并且存在反凝析现象,降低气相渗透率,减少气井产能。该研究使用Eclipse数值模拟软件中的组分模型,结合新疆某凝析气藏X19井地质及油藏工程资料建立单井模型,研究凝析气井生产过程中凝析油饱和度的分布状况、井底流压变化规律,以及配产气量、渗透率、生产时间等因素对于凝析气井生产动态的影响。

| Abstract: | The component of condensate system and its physical parameters varied with the change of the thermody-namic conditions such as pressure and temperature. Some physical and chemical phenomena such as interphase mass transfer and phase changes were occurred, and the retrograde condensate phenomenon lead to the reduction in gas relative permeability and well deliverability. Eclipse numerical simulation and geological and reservoir engineering data of Well X19 were used to establish single well model and study t... |
