摘　　要：周期注水是注水油田改善开发效果的主要方法,在调整油田高含水期工作中起至关重要的作用。本文从理论入手,探讨周期注水和脉冲注水提高采收率的驱油机理,提出周期注水的适用条件,以及脉冲压力、周期和次数对脉冲注水的影响,为多油层高含水油藏后期稳油控水提供可借鉴的资料。Cyclic water injection is the main method to improve the development effect of water injection field, and plays a vital role in adjusting the high water content of oilfield. This article starts with the theory of cyclic waterflooding and pulse water injection to improve recovery efficiency of oil displacement mechanism, put forward the suitable conditions of periodic water injection, and the influence of pulse pressure, cycle and times on the pulse water injection. Multiple reservoir water control in late high water cut reservoir stabilizing oil provides reference information.
