摘　　要：固井优质率是表征固井质量好坏的一个重要指标。影响固井优质率的因素很多 ,概括起来主要有三大类 :井眼状况因素、钻井液性能和固井施工参数。运用模糊数学的理论之一—多级综合评判方法对影响固井优质率的三大因素进行了综合评判 ,初步得出了哪一类因素起着主导作用的结论 。The cementing perfection rate is an important measurement to evaluate the cementing quality. Many factors affect cementing perfection rate, mainly including three groups: well figure, mud property and cementing operation parameters. we uses one of the fuzzy methods - the multiple comprehensive judgement to evaluate the factors. Finally, the factor which play a decisive role is presented, it provides a theoretical support for cementing operation and how to adjust and control the drilling as well as how to determine cementing parameters.
