摘　　要：尕斯油田注水开发过程中存在注水井注入压力长期居高、注水量较低等问题,解决的办法是注入纳米聚硅溶液。通过室内岩心流动实验,对聚硅材料增注效果、改善渗透率效果进行了分析评价。结果表明,纳米聚硅增注技术可以降低注水井的注水压力;提高油藏的吸水能力,实现增注;同时驱替实验也表明,选井选层是决定增注效果好坏的关键。Problems such as the high injection pressure and low water injection have existed for a long time in Gasi oilfield, which have seriously affected the oilfield development. This paper proposes ways to solve these problems by injecting nanometer polysilicon solution. This paper also analyzed the increasing injecting effect and permeability improvement of nanometer polysilicon through experiments. The results show that the technology of increasing injection of nanometer polysilicon could lower the injecting pressure of water injecting well and improve the water-intake profile, then achieve increasing water-injecting. Meanwhile, the experiments also show that selecting well and layer plays the key role in affecting the effect.
