摘　　要：张家垛油田位于苏北盆地南部海安凹陷,该油田阜三段油藏属于典型的致密砂岩油藏,储层总体表现为中等偏强水敏、强速敏、中等偏强碱敏,注水开发效果较差,开发难度较大。在该区开展CO2驱油技术研究对提高采收率具有重要意义。本文针对张家垛油田阜三段致密砂岩油藏性质,开展地层原油PVT物性分析和最小混相压力测试等方法进行理论研究,深入了解该区CO2开发增产机理。The reservoir of the third member of the Fu formation in the Zhangjiaduo oilfield is a typical tight sandstone reservoir located in the southern Hai’an County Sag of the Subei basin,development is more difficult.The study of CO2 flooding technology in this area is of great significance to enhance oil recovery.Based on the properties of the tight sandstone reservoir in the third member of Fujiang formation in Zhangjiadu Oilfield,the PVT property analysis of formation crude oil and the minimum miscible pressure test are carried out in this paper.
