聚合物水驱油是保证低渗油藏油井正常生产的重要措施,是提高采收率的有效手段。本文介绍通过分析聚合物水驱技术的发展现状,研究其驱油机理和驱油效果,指出阳离子聚合物驱油后水驱能够有效提高注水波及面积,通过分析其在孤东油田的应用,进一步指出其优越性,在石油开采工艺中有着广阔的应用前景。 Polymer water flooding is an important measure to ensure the normal production of oil wells in low permeability reservoirs and is an effective means to enhance oil recovery. This paper introduces the development status of polymer water flooding technology and studies its oil displacement mechanism and flooding effect. It is pointed out that water flooding can effectively increase flooding area after flooding with cationic polymer. By analyzing its application in Gudong Oilfield, Pointed out its superiority, it has a broad application prospect in petroleum exploitation process.
