| Abstract: | ��In this paper, the theoretical basis and method far determining the parameters in Bingham, Index and Casson Rheological Equations by using linear regression method are expounded. Through processing the measured data of ten kinds of drilling fluid and annlyzing and comparing the calculation errors of rheolugical parameters, determiued by several methods, it is indicated that the application of regression rheological parameters within the velocity-gradient limit of 1000-5S-1 has much higher accuracy. |
