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
