Abstract: Based on the geologic factors which have great effects on sandstone reservoir waterflooding, fuzzy comprehensive analysis is applied to formulate the indexes system and a new method of evaluating the effect of water displacement. The applying results in the such oilfields as Shuanghe and Ya Er Xia In Yumen show that the method is of characteristics of fewer data needed,
higher accuracy, more simplification and so on. And it is greatimportant to study a reservoir whether the formation is suitable for water injection or not

Key words: fuzzy comprehensive analysis, water drive oil reservoir, difficulty of waterflood
