| 摘 要： | 从影响岩石润湿性转变的一个重要原因——原油中沥青质在岩石孔隙表面的吸附出发，分别研究了注入水中含盐量的高低，以及注入水中阳离子的类型对原油中沥青质在岩石孔隙表面的吸附的影响，从而得出了影响岩石润湿性转变的重要因素。

| Abstract: | Proceeding from a cardinal reason affecting wettability reversal of rocks-the absorption of asphaltenes of oil in the pore surface of rocks, the effects of injection water salinity and cation type on this absorption are separately researched; thus the vital factors affecting wettability reversal of rocks are derived. |

| Keywords: | wettability asphaltene absorption wettability reversal |
