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 摘要從影響巖石潤(rùn)濕性轉(zhuǎn)變的一個(gè)重要原因原油中瀝青質(zhì)在巖石孔隙表面的吸附出發(fā),分別研究了注入水中含鹽量的高低,以及注入水中陽離子的類型對(duì)原油中瀝青質(zhì)在巖石孔隙表面的吸附的影響,從而得出了影響巖石潤(rùn)濕性轉(zhuǎn)變的重要因素。
