摘　　要：下二门油田H2Ⅱ油组二次聚驱前,通过微观可视模型进行二次聚驱驱油实验,表明在非均质油藏中进行高浓度二次聚驱,可以通过进一步改善油水流度比而提高油藏采收率。同时实验报告了水驱、一次聚驱、二次聚驱各个阶段的主要波及区域范围及驱油效果。Displacement experiments of secondary polymer flooding by micro visual model show that recovery can be enhanced through improved oil-water mobility ratio for non-homogeneous reservoir before secondary polymer flooding in H2 Ⅱ oil group of Xiaermen oilfield.Sweep region and flooding effect in various stages for water flooding,primary polymer flooding and secondary polymer flooding are reported at the same time.It is an important reference that optimization chemical flooding for further enhanced oil recovery at the end of water-drive after primary polymer flooding at home and abroad
