ABSTRACT
To address the problems of many objective influencing factors and complex weight determination in the multiple grading compact stacking model of cementing slurry, this paper fully reflects the influence of objective factors based on the original weight determination method. The influence of subjectivity in weight determination is weakened to the maximum extent, and for each indicator that can be quantified. The hierarchical analysis method is used as the basis to determine each indicator through the measurement comparison between the values of each indicator for cases where the factors could not be quantified. The weight was determined objectively using gray-scale correlation analysis. The results show that the improved hierarchical analysis and the gray-scale correlation analysis can objectively determine the weight of the relevant factors and indicators, which can solve the problems of determining the weight of the influencing factors in the multiple grading of cementing slurry.
