摘　　要：选用不同的流变模式对钻井水力参数的计算影响很大。文中对石油钻井中常用的4种钻井液流变模式:幂律模式、宾汉模式、卡森模式以及带屈服值的幂律模式进行了对比和分析,并对钻井液流变模式进行优选的4种方法,即流变曲线对比法、剪切应力误差对比法、相关系数法和最小二乘法做了详细的阐述。Appling different rheological models would cause in great effect on calculation of drilling hydraulic parameters. This paper contrasted and analysed four types of conventional rheological models as Bingham, Power law, Casson and HB, and detailedly elaborated four different optimization methods of drilling fluids as rheological curve correlation, shear stress error correlation, correlated parameters analysis and least square method.
