井楼油田北区油水分布研究

A Study on Oil-water Distribution in the North of Jinglou Oilfield

通过构造、油水剖面分布以及油水平面分布研究,阐明了井楼油田北区下第三系核桃园组核三段Ⅳ、Ⅴ、Ⅵ油组油水分布特征,解决了高部位出水、低部位出油的问题。研究认为,核三段地层的油水分布主要受构造与断层控制,其次是沉积微相和岩性控制。研究成果为开发区内综合调整及外围挖潜提供了坚实的依据。

Through studying the distribution of structures,oil-water profile and its plane,the distribution characters of oil and water in the Ⅳ,Ⅴ and Ⅵ members of the Tertiary Eh3 in the north of Jinglou Oilfield were denoted ,by which the problems of water producing in the high position and oil producing in the low position .The study shows that the oil-water distribution in Eh3 is controlled by the structure and fault zones and as well as sedimentary facies and lithologic property.It provides a stable basis for a comprehensive adjustment and tapping the potential in adjacent wells.
