Abstract： Currently, the high water cut oilfield in eastern China have met many technical bottleneck problems that underground oil-water systems need to be rebuilt and well-patter need to be improved further. Based on the development data from 47 foreign high water cut sandstone oilfields, the waterflood development characteristics of foreign high water cut oilfields were summarized, and the redevelopment techniques and measures in high water cut stage of them were analyzed in detail. Furthermore, the new theories and technologies on geology, reservoir engineering and technology were also discussed. These measures adopted in foreign high water cut sandstone oilfields can provide certain guidance for improving waterflood recovery efficiency in similar oilfield of eastern China.
