摘　　要：在研究影响砂岩油藏水驱难易程度的诸多地质因素基础上，引用模糊数学中模糊综合评判方法，构成了评价水驱难易程度指标体系及评价方法。该指标体系与评价方法应用于双河油田与玉门鸭儿峡五区表明，这种方法具有所需的数据量少，准确简便等优点。尤其在油田注水之前，研究地层是否适合注水及注水的难易程度有一定的实际指导意义。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 great important to study a reservoir whether the formation is suitable for water injection or not
