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相态测试方法,并与常规凝析油-气两相平衡体系的PVT测试结果进行了对比,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。The effect of gaseous condensate - water on condensate - gas system used to be ignored in conventional condensate-gas system phase behavior test. Condensate gas reservoir exploitation practice 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 considering 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 conventional oil/gas two - phase equilibrium system test results, and analyzed how the gaseous water content affect the condensate - gas system.
