摘要： 通过建立大庆萨尔图油田北二西试验区油藏的化学驱模型,模拟研究了包含主段塞、副段塞、前置段塞和后置段塞的碱、表面活性剂和聚合物三元复合体系化学剂含量、段塞大小及矿场注入速度对驱油效果的影响。主段塞中碱的质量分数和表面活性剂的质量分数对采收率的影响十分显著,而且都存在使采收率达到最大值的合理质量分数。无论是三元主段塞或副段塞,增加聚合物的质量浓度,对提高采收率的贡献都很明显。各段塞的大小对驱油效果都有不同程度的影响。

Abstract: The chemical flooding model for reservoir of Bei'erxi pilot area in Daqing Saertu oilfield is developed, by which the influences of chemical concentration, slug size and injection rate to oil displacement efficiency with alkali-surfactant-polymer folding system containing main slug, auxiliary slug, pre-slug and over-slug are simulated, respectively. The results show that in the main slug the alkaline and surfactant concentrations have obvious effects on the oil recovery. And each of them has an optimal value relating to maximum recovery. Increasing polymer concentration of either alkali-surfactant-polymer main slug or auxiliary slug will significantly improve the incremental oil recovery. Change of sizes of these four slugs will result in change of EOR to a certain extent.

Key words: alkali-surfactant-polymer flooding, numerical simulation, EOR, Daqing oilfield
