摘　　要：油藏岩石的润湿性是岩石——流体综合作用的结果,润湿性受多种因素的影响,注入水水质影响油藏岩石的润湿性。本文从原油中沥青质在岩石孔隙表面的吸附出发,研究了注水过程中水中的细菌和悬浮物对油藏岩石润湿性的影响,对注水开发有很好的指导意义。Wettability of reservoir rocks is the result of rocks and liquids, interact. Wettability is affected by many factors. Injection water quality can affect the Wettability of reservoir rocks. This paper proceeding from a cardinal reason affecting wettability reversal of rocks-the absorption of asphaltenes of oil in the pore surface of rocks ,investigated the effect of microbe and suspension to the wettability in the injection water ,it is have good guidance senses for the Injection water exploitation.
