| 摘 要： | 关于多孔介质对凝析气露点的影响 ,不同学者实验研究得出的结论各不相同 ,有的结论甚至相反 ,但目前还没有一种理论能较好地解释这种矛盾现象。文中建立了一种考虑多孔介质毛管压力和吸附作用影响的露点压力计算理论模型 ,针对实验室和实际地层两种条件进行了计算和分析 ,说明了造成实验结果差异的原因 ,并阐述了地层条件下多孔介质对凝析气露点的影响趋势。

| Abstract: | For the effect of porous media on dew point of gas condensate,different researchers have reached different or even contrary conclusions.But up to now,there is no theory that can well explain this contradictory phenomenon.In this paper,a theoretical model of calculating dew point is presented,which considers the effect of capillary pressure and adsorption in porous media.Calculation and analysis are performed for a laboratory condition and a real formation,and the causes that may make experimental results different are described.The paper also illustrates some trends of porous media effect on dew point in a gas condensate reservoir |
