Rheological Model Optimization of Non-solid Phase Drilling Fluid in Daniudi Gas Field

Abstract:

It was showed by the example calculation of non-soil phase drilling fluid in Daniudi gas field that the correlation coefficient of Herschel-Bulkley model was the largest with the smallest residual sum of squares; than was the Casson and power-law model; Bingham model was the worst. Herschel-Bulkley model was suggested.
