摘要

本文利用模糊数学原理,给出了钻头的多因素综合评判方法,并结合塔里木轮南地区36口井的现场资料进行了综合评判,其结果与单位钻进成本选型方法进行了对比,二者的符合率为86%。文中对专家评分机理的探讨及用熵对专家评分机理的定量描述,可为权向量的确定提供一个较为有效的方法。

Abstract

In this paper,a multiple factors synthetical evaluation method of bits is given by using the fuzzy mathematics,The synthetical evaluation is conducted with the field information for 36 wells in the Lunnan oil field,Talimu,The results are compared with the selection model method s according to the drilling cost per meter and the compatibility rate reaches 86%.In this paper,the study about the expert evaluation mechanism and the quantitative description about the expert evaluation with the entropy can provide on effective method for the determination of the weighted vector.
