摘要: 油田进入中高含水期后,研究剩余可采储量的分布规律是调整、挖潜的物质基础,而准确计算单井的水驱控制储量是分析剩余油分布的重要方法。通过分析单井的水驱特征,认为由于储层物性的差异和水驱控制程度的不同,单井之间的开发动态差异大,单井间的水驱控制储量相差悬殊;在油藏的开发过程中,储量会发生再分配,部分单井会“借走”邻井的储量,使其水驱控制储量比地质储量大。因此,评价研究单井的水驱控制储量具有现实意义。

Abstract: During the medium -late water cut stage ,it is an important approach blaccurutely to estimate the waterflooding controlling reserve of a single well to studies reservoir residual oil distribution ,and the oil field adjustment measures are foundation .In this paper ,after analyzing the waterdrive characteristics of a single well in detail , we come to the following conclusions that:1.due to formation heterogeneity and different waterdrive intensity,the difference of development behavior among oil wells is significant and so is the waterflooding controlling reserve,2.In the development process of reservoir, reserve would be redistributed ,and some wells would”borrow”reserve from
adjacent wells ,which will lead to greater waterflooding controlling reserve than geology reserve in a single well. Therefore,itis of application significance to study waterflooding controlling reserve of a single well.

Key words: reservoir, water drive, reserve evaluation, residual reserve
