  • The so-called API's “two-point” method for rheological calculation often produced big errors in the calculation results which are often different than the data collected in field operations. A modified calculation method is presented based on the principle of the “two-point” method, combining the calculation method for shear rate of fluid near the wall of pipes. Data of laminar flow of two drilling fluid samples, A and B, were collected in laboratory experiments and used to verify the accuracy of the modified method. The verification shows that the modified method is more accurate than the API's method in calculating pressure drop of laminar flow. For example, Bingham rheological parameters of the fluids A and B calculated with the modified method were used to calculate the pressure drops in pipe laminar flow, the calculation errors were 17.61% and 40.19% less than the errors generated by the old “twopoint” method, respectively.
