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 ,为固井作业施工以及如何合理地进行调控钻井参数和固井作业参数提供了理论依据 Cementing quality is a sign of cementing quality is an important indicator of quality. There are many factors affecting the cementing quality rate. There are three main categories to summarize: wellbore condition, drilling fluid properties and cementing construction parameters. Applying the method of multi-level comprehensive evaluation, one of the theories of fuzzy mathematics, to make a comprehensive evaluation of the three factors that affect the cementing quality rate, it is concluded that which type of factors play a leading role. This is the conclusion of cementing operation construction and how Reasonable regulation of drilling parameters and cementing operation parameters provide a theoretical basis
