| 摘 要： | 本文从大庆油田油层非均质特点出发，设计并制作了渗透率迹异系数为０．６８的非均质油层物理模型，通过三种不同分子量聚合物在该物理模型上的驱油实验，证实了聚合物分子量与驱油效率之间的内在关系，这将为大庆油田聚合物驱最佳分子量选择提供实验依据。

| Abstract: | Starting from the heterogeneous characteristics of reservoir in Daqing oil field .a physical model of heterogeneous reservoir with permeability variation coefficient of 0. 68 isdesigned and made. Through oil displacement experiment on this model by usuig three kindsof polymer with different molecular weight ,the internal relation between polynier molecularweight and sweep efficiency is confirmed ,which will provide experimental basis for optimumpolymer molecular weight selection in Daqing oil field. |
