【摘要】 根据旋转粘度计设计原理导出幂律、宾汉、卡森等非牛顿流体流变性测试结果的修正系数。同时根据最小二乘法原理得出确定非牛顿流体流变参数的回归分析方法。应用回归分析法和二点法对大庆6种不同类型的钻井液流变参数分别进行计算。其结果表明回归分析法远好于二点法。更多还原

【Abstract】 The revised coefficients of rheology survey data on power-law, Bingham and Cas-son fluids are produced on the principle of rheometer. The regression method of rheolo- gy parameter for non-Newtonian fluid is obtained by the least square method. The 6kinds of drilling muds, rheology parameters are calculated by using the regression andthe two-point method. The results reveal that the regression is by far better than thetwo-point. method.更多还原
