Optimization of Fracturing Scheme Based on Grey Correlation Analysis and Multistage Fuzzy Evaluation
Aiming at the problems of traditional fracturing optimization methods such as relying solely on simulation calculations and lack of systematic analysis,this paper comprehensively considers the influence of reservoir parame-ters and fracture parameters on the fracturing effect,and studies the scientific evaluation method of fracturing schemes.First,the gray correlation method is used to obtain the correlation degree of each influencing factor and sort it,and then the correlation degree is normalized to determine the weight,and each factor is analyzed separately.Fi-nally,the index eigenvector matrix and the index membership degree matrix are established,based on the maximum membership In combination with the established two-level comprehensive evaluation model,complete the evaluation and optimization of fracturing schemes.The results show that in the optimization of the comprehensive fracturing plan,a more scientific selection result can be obtained through multi-factor indicators and different degrees of influ-ence.This method improves the traditional fracturing optimization method,and makes the evaluation and optimiza-tion of the fracturing plan more reasonable and reliable.
