摘要: 常规凝析油气体系PVT相态测试方法忽略了气态凝析水对凝析油气体系相态的影响,而国内外凝析气藏开发实践表明,气态凝析水对凝析油气体系相态特征的影响不应被忽略.为了更有效地指导凝析气藏的开发,必须建立考虑气态凝析水的凝析油气体系PvT相态测试和计算方法探索设计了富含气态凝析水的凝析油气体系PVT相态刚试方法,并与常规凝析油一气两相平衡体系的PVT测试结果进行了甘比,分析了考虑气态水组分的存在对凝析油气体系相态的影响

Abstract: The effect of gaseous condensate-water on condensate-gas system used to be ignored in conventional condensate-gas system phase behavior test. Condensate gas resewoir exploitation prac-lice in home&abroad indicated that the effect of gaseous condensate-water on condensate-gas system phase behavior should not be ignored. So to instruct the condensate gas reservoir exploitation more efficiently, we must set up the condensate-gas system PVT phase test and compute the method of the consider-ing gaseous condensate-water. In this paper, we tried to explore and design the condensate-gas system PVT phase test method with abundant condensate-water, compared with the convention-al oil/gas two-phase equilibrium system test results, and ana-lyzed how the gaseous water content affect the condensate-gas system.

Key words: condensate gas reservoir, high-temperature&, high-pressure, condensate-water, oil/gas/water multi-phase e-quilibrium, PVT phase test
