【摘要】 凝析油气体系和储层多孔介质是一个相互作用的系统 ,考虑多孔介质界面现象对凝析油气体系相平衡规律和渗流规律的影响 ,能更真实地反映凝析油气体系在储层多孔介质中的相态特征和渗流特征 ,从而更准确地认识凝析气藏的开发动态规律 ,以便更为合理、有效地开发凝析气藏。针对我国某个实际凝析气藏 ,利用研制的相态模拟分析软件分别对该凝析气体系的毛管压力、露点压力和恒组成膨胀过程中反凝析液量进行了相态模拟计算 ,得出了毛细管压力对凝析气体系相平衡影响的结论。更多还原

【Abstract】 The gas condensate fluid and the porous media is an interaction system.lt is more really to reflect the phase behavior and the percolation characteristic of a gas condensate system,taking account of the effect of the interfacial phenomena on the phase equilibrium rule and the percolation rule of a gas condensate system in the porous media.As a result,the production performance of a gas condensate reservoir can be recognized well and then can be exploited effectively.The capillary pressure,the dew point pressure,and the retrograde liquid volume of the constant compositional expansion are calculated for a practical gas condensate system by using the software of phase simulation and analysis.The conclusion of the capillary pressure effect on this system is educed out at the end of this paper.更多还原
