| 摘 要： | 应用聚硅纳米材料在油田注水井中降压增注的室内实验表明，纳米聚硅材料能够改变岩石润湿性、提高水相相对渗透率，一同时说明聚硅材料易吸附于岩石表面能改变界面性质，其强憎水特性能够驱替吸附在孔隙内表面的水膜，扩大孔径．所以纳米聚硅材料能降低注水压力，提高注水量，具有较好的经济效益．

| Abstract: | According to experimental study of ecompression and augmented injection of polesilicon in oil-field,the nanometer polesilicon can improve the waterflood response by changing the wettability of rock,enhancing relative permeability of water,and reducing significantly the flow resistant of injection water because of its stronger hydrophobility through core driving experiments and micro driving test.Polysilicic material can decompress and augment injection.Its best economic profit can be proved through economic evaluation. |

| Keywords: | polysilicic material low-permeability oil reservoir decompression and augmented injection relative permeability wettability adsorbability |
