摘　　要：长庆油田华201区开发储层为低渗透储层，经过多年的开发后，各种矛盾突出，常规注水已不能进一步有效提高最终采收率，三次采油技术中，聚合物驱油技术成熟，在该区进行注聚合物，以改善开发效果、提高采收率。，本文通过室内试验对华201区低渗透高含盐油藏驱油聚合物的流变性进行分析研究，确立聚合物的浓度、应用温度、剪切速率、剪切时间等是影响流变性的主要因素，为现场应用提供了有力依据。Development reservoirs of well Hua201 area in Changqing Oi]field are low permeability reservoirs. After development for years, various contradictions are prominent. Conventional water injection has been unable to further improve the ultimate recovery. In the tertiary oil recovery technology, polymer flooding technology is matured. Polymer is injected in the area to improve the development performance and enhance oil recovery. The paper analyzes and studies rheolngy of polymer of Hua201 Zone low permeability oil reservoirs thrnugh laboratory tests and confirms that polymer concentration, applied temperature, shear rate, shear time and the like are main factors that affect the rheology, which provides strong basis for field application.
