分别用人造岩心和人造均质平面模型，在实际油层条件下研究了辽河油田齐40稠油油藏实施水级及聚合物驱的室内驱油效率及级替特征。在驱油实验中用核磁共振成象技术研究了稠油油藏水驱和聚合物驱的驱油机理。结果表明，在一定条件下，稠油油藏在蒸汽吞吐后实施聚合物驱是可行的；聚合物驱主要通过扩大波及范围和增加驱替压差来提高驱油效率；聚合物驱后仍有大量的残余油滞留在孔隙介质中。
The artificial flooding and artificial flooding efficiency and gradation characteristics of Qi 40 heavy oil reservoirs in Liaohe Oilfield were studied by artificial cores and man-made homogeneous planar models, respectively. In flooding experiment, the mechanism of water flooding and polymer flooding in heavy oil reservoirs was studied by using nuclear magnetic resonance imaging technique. The results show that under certain conditions, it is feasible for heavy oil reservoirs to carry out polymer flooding after steam huff and puff; polymer flooding can improve the flooding efficiency mainly by expanding the reach and increasing the displacement pressure difference. After polymer flooding, Large amounts of residual oil remain in the pore medium.
