中文摘要：

凝析油气体系相平衡是在储层多孔介质中进行，多孔介质中凝析油气相变是凝析气藏开发研究者关注的主题。应用二维刻蚀玻璃微观孔隙模型，通过可视化技术，对凝析气微观气液两相相变特征进行了研究，并对多孔介质吸附和毛细凝聚对凝析气相变的影响进行了分析。

英文摘要：

It is at reservoir in porous media proceed to condensate gasses system phase equilibria, which attracts attentions of reservoir engineers. With application of Microvisual technology in sculpture glass network model, gas-liquid phase change characteristics were studied by gas condensate microvisual method. Effect factors of porous media including adsorption and capillary agglomeration were clearly analyzed on gas condensate change.
