摘要
采用分子自组装技术使岩心表面亲水性岩层的润湿性发生反转成为亲油表面。改变逆向毛管力方向使之变为自吸驱动力,进而提高原油采收率。
The core wettability was alternated by molecular selfassembly technique, which can change core wettability from hydrophobic to hydrophilic. And it can further enhance oil recovery due to capillary imbibition oil displacement at bottomhole formation area.
