Abstract :
During the oil drilling process, the quality of cementing directly impacts on following operations. According to the operating procedure of cementing, this paper classifies the effecting factors of cementing quality to two types. Classification one is displacement efficiency and another is WOC (Wait on Cement) effect. Through the methodology of multi-level fuzzy comprehensive evaluation, and via the computation of “weighted average-type”, the model of multi-level fuzzy comprehensive evaluation for cementing quality is constructed.
