摘　　要：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。ccording to the heterogeneous characteristics of reservoir in Daqing oil field,a physical modelof heterogeneous reservoir with permeability variation coefficient of 0.88 is designed andmade. Experiments have been made to study the effects of the molecular weight,viscosity andshear degradation of polymer on polymer flooding. The research results will provide experi-mental basis for the selection of optimum molecular weight for polymer flooding in thick oilreservoirs of Daqing oil field.
