本文从大庆油田油层非均质特点出发，设计并制作了非均质油层物理模型，运用它进行了聚合物分子量、粘度以及剪切降解作用等因素对驱油效果影响的实验研究。研究结果将为大庆油田厚油层聚合物驱最佳分子量选择提供实验依据。
Based on the heterogeneity of reservoir in Daqing Oilfield, a physical model of heterogeneous oil layer is designed and fabricated. The effects of polymer molecular weight, viscosity and shear degradation on flooding effect are studied. The results will provide the experimental evidence for selecting the optimal molecular weight of polymer flooding in the thick oil layer of Daqing Oilfield.
