本文采用数值模拟方法,选取大庆油田采油一厂北一区321块已结束注聚区的典型井组,利用其静态资料,分别对聚驱注入速度、聚合物相对分子质量、注入浓度、井组注采对应率、井距5方面影响因素运用数值模拟的方法进行研究。在一定范围内注入速度越大、聚合物相对分子质量越大、注入浓度越大、注聚越早、油层连通关系越好、井距越大,提高采收率效果越好。
In this paper, the numerical simulation method is used to select 321 wells in Beih district of Daqing oilfield, the end of a typical well group. Using the static data, the effects of polymer flooding injection rate, polymer relative molecular mass, injection concentration, well group Note the mining correspondence rate, well spacing 5 factors affecting the use of numerical simulation methods to study. In a certain range, the larger the injection speed is, the larger the molecular weight of the polymer is, the larger the concentration of the polymer is. The larger the concentration of the polymer is injected, the earlier the polymer is aggregated. The better the connectivity of the oil layer is, the larger the well spacing is and the better the recovery is.
