东濮凹陷深层低渗凝析气藏类型判别研究

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。

Study on Type Differentiation of Deep Gas-Condensate with Low Permeability in Dongpu Depression

It is difficult to distinguish the type of gas reservoir because of particularity and complexity of deep gas-condensate reservoirs with low permeability in Dongpu depression.This paper makes fully use of many types of property indexes of the fluid to study reservoir type,saturation characteristics,characteristics of oil rim and variety of fluid property in vertical direction of deep gas-condensate reservoirs such as Qiaokou,Baimiao and Pu 67,etc.According to the phase characteristics,condensate gas and oil system are compartmentalized.The type of gas reservoir is differentiated distinctly by applying the above achievements and important basis is provided for developing the gas reservoir reasonably.
