Rheological behavior and temperature dependency study of Saraline-based super lightweight completion fluid

摘要: Abstract This article presents a rheological and statistical evaluation of Saraline-based super lightweight completion fluid (SLWCF) its effect on operating temperature. In this work, eight models, namely the Bingham plastic, Ostwald–de Waele, Herschel–Bulkley, Casson, Sisko, Robertson–Stiff, Heinz–Casson, Mizrahi–Berk, were used to describe behavior fluid, results compared with Sarapar-based SLWCF. The showed that was best described by both Sisko Mizrahi–Berk models. These two models seem be able not only relationship between shear rate stress accurately but also accommodate physical characteristics fluids. study viscosity dependency temperature, experimental data SLWCF almost doubled Furthermore, activation energy seemed decrease dramatically for fluids at low tended remain constant higher rate. However, less dependent could power equation. Results more sensitive temperature changes rates.
