With the extension of oilfield development time,the conventional water injection sweep scope is relatively fixed,and the technical adaptability is gradually deteriorating.It is an effective method to improve oil recovery by using the cycle of water injection volume in-creasing or decreasing or water injection well stop-start.This article proposes to conduct oil well linkage testing on well groups with multiple cycles of water injection,that is,to monitor the changes in bottom hole flow pressure of injection wells and production wells during the periodic changes in water injection volume or the process of stopping and starting injection,in order to optimize the fluctuation amplitude and period of unstable water injection.This method is simple to operate and less affected by external factors,which is suitable for pa-rameter optimization in different unstable water-injected reservoirs.
