摘要
考虑多孔介质界面现象对挥发油气体系相平衡规律和渗流规律的影响,能更真实地反映挥发油气体系在储集层多孔介质中的相态特征和渗流特征,从而更为准确地认识挥发油藏的开发动态规律,以便更合理、有效地开发该类油藏。针对我国某一挥发性油藏,利用研制的相态模拟分析软件分别对该油气体系的毛管压力、泡点压力和恒组成膨胀过程中液相含量和相对体积进行了相态模拟计算,认为毛细管压力对挥发油气体系相平衡起着复杂而重要的影响。
In order to really reflect the characteristics of phase behavior and percolation of a volatile of oil system in reservoir porous media,the effect of the interfacial phenomena on the phase equilibrium rule and the percolation rule should be taken into account in the porous media for a volatile oil system.As a re-sult,the production performance of a volatile oil reservoir can be recognized well and then can be exploited effectively.The capillary pressure,the bubble point pressure,the liquid content and the relative volume of the constant compositional expansion are calculated for a practical volatile oil-gas system by using the software of phase behavior.The conclusion of the great effect of capillary pressure on this system is drawn in this paper.
