摘要
为了提高窄小河道砂体储层聚驱开发效果,在分析聚驱动态变化特征基础上,根据不同的注聚阶段、不同的砂体发育分别采取不同的注入参数和综合调整方法。纯油区东部的北二东西块采取上述调整措施后,取得了较好的增油降水效果,此方法可以指导其他区块的调整和二类油层注聚。
In order to improve the polymer flooding development effect of small channel sand reservoir, based on dynamic variable characteristics, different injection parameters and integrated adjustment method are adopted for different injection periods and sand body development degree. Favorable development effect has shown in the west of Block Beierdong in eastern area of net oil flooding since the modifications have been performed. This method can also provide direction for adjustment of other blocks and ClassⅡreservoir.
