摘要
凝析气藏与一般的“黑油”气藏不同 ,如果用“黑油模型”加以研究开发 ,会造成大量的凝析油滞留于地下而采不出来 ,有时还会造成油环和气顶油气互窜 ,从而降低采收率。因此 ,我们只能选用更为精确的“组分模型”作为凝析气藏模型 ,并对凝析气藏进行相态分析 ,文章还运用数值模拟软件相态模拟分析软件包DESKTOP
Condensate gas reservoir is different form the common 'heavy oil'.A great deal of condensate oil stays underground and can′t be developed,if we applied the 'heavy oil' model to development.Sometimes it will exchange the oil ring and gas cap so that recovery reduces.So more accurate 'component model' is adopted to condensate gas reservoir.Meantime we analyse its phase.This paper applies the numerical simulation and phase analyse software(DESKTOP-PVT).
