摘　　要：胜利油区低渗透油藏普遍存在注水压力高、吸水能力差、开发效果差等问题。应用纳米技术,开展了低渗透砂岩油田提高注水能力实验。聚硅纳米材料对岩心的润湿性影响和增注实验研究发现,采用合适的聚硅纳米材料处理岩心,能够改变岩石润湿性,可以较大幅度地提高岩心的渗透率,改善注水效果。High injected water pressure, poor water absorbing capacity, poor development effect and some other questions generally appear in low permeability oil reservoir of Shengli petroliferous province. Experiments of enhancing injection capacity in low - permeability sandstone reservoir are conducted by nanometer technology. Research on the influence of polysilicic nanometer material on core wettability and augmented injection found that the core treated by polysilicic nanometer material with proper size may change rock wettability, enhance core permeability by a big margin and improve water-flooding effect.
