Abstract: Optimum casson parameters play a very important part in modern drilling engineering design,jet drilling and optimized drilling.This paper discusses all kinds of methods for determining casson parameters,and analyzes the advantages and disadvantages of these methods.This paper analyzes and studies from a theoretical point of view a new method for determin-ing casson parameters largely for larger dispersion data system processing-Gray systemstatic method.Its application is shown by acfual examples.

摘要： 本文指出了最佳卡森参数对现代钻井工程设计、喷射钻井、优化钻井的重要性,概述了目前确定卡森参数(η_∞,τ_C)的各种方法,并分析了各自的优缺点;对离散性较大的数据系统的处理从理论的角度分析研究了确定卡森参数的新方法──灰色系统静态法的可行性,并举例说明其应用。
