大庆油田聚合物驱油工业化推广应用研究

COMMERCIAL APPLICATION OF POLYMER FLOODING

对大庆油田聚合物驱油工业化推广应用的驱油效果进行分析研究以后，认为聚合物的驱油效果除了与已经研究过的聚合物的分子量、溶液浓度、用量、注入速度和注入方式等工艺技术条件有关外，还与地质条件和含油饱和度等因素有关。目前，大庆油田聚合物驱油已经取得了提高采收率2．01％的明显效果，预测最终采收率可提高13．0％左右。

After analyzing and researching the driving-oil effect of commercil polymer flooding in Daqing oil field. We come to aconclusion: The driving-oil effect of polymer flooding not only has relations with technology conditions which have beenresearched, such as molecular weight, concentration, injection velocity, injection manner of polymer solution, but also hasthe relations with geological conditions and oil saturation, etc.. At present, an 2. 01 % increment of recovery factor has beenobtained. It is predicted that the final recovery factor will increase by 13. O% or so.
