基于模糊数学和灰关联分析的多因素综合评判方法优选完井方式

Optimization of Well Completion Methods With Multi-factor Comprehensive Evaluation Method Based on Fuzzy Mathematics and Grey Correlation Analysis

采用模糊数学和灰关联分析相结合的多因素综合评判方法进行完井方式优选,克服了单独使用模糊综合评判时权重集人为赋值的片面性,使评价更加客观全面合理。首先分析影响完井方式选择的因素,然后建立完井方式优选的多因素综合评判理论模型,最后进行了实例计算。

The multi-factor comprehensive evaluation method based on fuzzy mathematics and gray relational analysis was adopted to optimize well completion methods,which can overcome the one-sidedness of man-made assignment of weight set when only using fuzzy comprehensive evaluation method,make the evaluation more objective,comprehensive and reasonable.Firstly,factors to affect well completion optimization were analyzed,and then a multi-factor comprehensive evaluation theoretical model of well completion optimization was established,at last example calculation was carried out.
