A fracturing effect evaluation and parameter optimization method based on fuzzy comprehensive evaluation method
The fracturing effect is influenced by many process and geological factors.This article uses the grey correlation method to calculate the weights of each influencing factor,and then applies the fuzzy comprehensive evaluation method to calculate the process score and geological score respectively based on the weights and membership functions of each factor.Furthermore,the analytic hierarchy process is used to calculate the weights of the process score and geological score,thereby calculating the comprehensive score of a single well.The results calculated by this method have a high degree of matching with the unob-structed single well.By adjusting the process parameters to improve the comprehensive score of a single well,the fracturing process parameters can be optimized,and the optimization re-sults can be verified through PT software.This article has important reference significance for fracturing construction and provides a reliable basis for optimizing fracturing construction design and evaluating fracturing effectivenesss.
