摘要
东濮凹陷深层低渗凝析气藏的特殊性和复杂性导致了气藏类型判别的难度, 充
分利用各种流体特征指标, 从大类判别、饱和特征分析、带油环特征判别、流体纵向变化特征等
方面对桥口、白庙、濮67等深层凝析气藏展开研究, 并依据相态特征对凝析气和平衡油体系进
行了划分, 较准确地判别了这些主要气藏的类型, 为气藏的合理开发提供了重要的依据。
Abstract
It is d ifficult to d istingu ish the type o f gas reservo ir
because o f particular ity and comp lex ity of deep gas -
condensate reservoirs w ith low perm eab ility in Dongpu
depress ion. This paper m akes fu lly use o f m any types of
property indexes of the flu id to study reservo ir type,
saturation character istics, characteristics o f o il r im and
va riety o f flu id property in vertical d irection o f deep gas -
condensate reservo irs such as Q iaokou, Ba im iao and Pu 67,
etc. A ccording to the phase character istics, condensate gas
and o il system are compartm enta lized. The type o f gas
reservo ir is d ifferentiated distinctly by app ly ing the abov e
ach ievem ents and im portant basis is prov ided for deve lop ing
the gas reservo ir reasonably.
