摘　　要：流体相态特征研究的目的是为分析地层流体相态变化、评价地层反凝析污染动态,及时进行生产动态调整提供依据。同时为确定凝析气藏合理开发方式的数值模拟研究提供相态拟合、基础注气开发机理分析、注气量与注气时机优选所必须的地层流体PVT相态特征热力学参数。以雅克拉-大涝坝凝析气藏为例,开展了雅-大凝析油-气-水三相体系相态特征研究,论述了平衡共存水存在下目前和原始富含气态凝析水的地层凝析气流体PVT相态特征。To study the phase behavior of formation fluid is for(1) analyzing the behavior change,(2) evaluating the retrograde condensate pollution,(3) providing some evidence for adjusting production performance in time;(4) presenting the phase-behavior match,the analysis on basic injection development mechanism,and some thermodynamic parameters of PVT phase behavior required for optimization of both injection volume and time.In this paper,not only the three-phase system(condensate oil-gas-water) in Yakela-Dalaoba condensate gas reservoir is studied;but also the PVT phase behavior of formation condensate gas with rich gaseous condensate water during the existence of balanced connate water is presented.
