摘　　要：周期注水是水驱开发油田改善开发效果的一种水动力学方法。结合双河油田Ⅳ４层系地质特征分析了周期注水试验效果及开发特点。５口注水井进行矿场实验：单元日产油最高增加２１ｔ，综合含水最低下降２个百分点。周期注水井对应受效油井的年产油量比常规水驱增加 ６０２７ｔ，年含水上升率比试验前下降 １个百分点。Cyclic waterflooding is an effective hydrodynamic method to improve oilfield development effects. Cyclic waterflooding experimental results and development characteristics are analyzed in conjuncton with the geological features of IV 4 series of strata in Shuanghe oilfield. Five wells are put into field experiment with the maximum incremental unit daily output of 21t and the minimum total water cut decrease of 2 percentage. The annual output of the affected producers corresponding with cyclic water injectors is 6027t higher than that of conventional waterflooding and annual water Cut increasing ratio is 1 percentage lower than that before experiment.
