摘要: 双河油田437 块Ⅱ 4–6 层系是一个典型的半封闭边水油藏,边水活跃,目前油藏进入特高含水期,单元采出程度45.82%,综合含水率高达97.8%。根据储层地质资料,采用协同克里金确定性建模方法建立了双河油田437 块Ⅱ 4–6 层系的三维地质模型。利用三维地质建模成果,结合储层地质特征、地层流体性质以及油藏生产动态资料,采用油藏数值模拟的方法,得出目前双河油田437 块Ⅱ 4–6 层系剩余油的分布特征及剩余油富集区域,为开发方案调整,高含水期剩余油挖潜提供了可靠的依据。

Abstract: Shuanghe Oilfield 437II4–6 is a typical semi-closed edge water reservior. Edge wate is active in this area, and reservoir is now in the development phase of extra high water cut period currently. The unit recovery efficiency 45.82%, and water percentage 97.8%. By using reservoir numerical simulation method and according to reservoir geology, 3D geological model of Shuanghe oilfield 437II4–6 is established, and the distribution data of remaining oil and residual oil region of Shuanghe Oilfield 437II4–6 are obtained. The basis for adjusting development plan and for digging the potential of remaining oil in high water cut period was provided.

Key words:

semi-enclosed edge water reservoir, high water cut period, reservoir, numerical simulation, remaining oil distribution, Shuanghe Oilfield
