摘　　要：针对传统压裂优化方法存在的单纯依靠模拟计算、缺乏系统性分析等问题,本文综合考虑储层参数和裂缝参数对压裂效果的影响,研究了压裂方案科学评价方法。首先,采用灰色关联法得到各影响因素的关联度并排序,随后对关联度归一化处理确定权重,并对各因素进行单独分析,最后建立指标特征向量矩阵和指标隶属度矩阵,基于最大隶属度原则,结合建立的二级综合评判模型,完成压裂方案的评判优选。结果表明,在综合压裂方案优化中,通过多因素指标、不同影响程度,可以得到更科学的选择结果。该方法改进了传统压裂优选方法,使压裂方案的评价和优化更加合理可靠。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 parameters 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.Finally,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 influence.This method improves the traditional fracturing optimization method,and makes the evaluation and optimization of the fracturing plan more reasonable and reliable.
