摘      要：This research examined the use of 75 nm zinc oxide nanoparticles(nano ZnO)and polyethylene butene(PEB)to decrease the viscosity of Nigerian waxy crude *** rheology of the crude oil was assessed by measuring the viscosity and shear stress of samples containing PEB at 500,1000,2000,3000,4000 or 5000 ppm and nano ZnO at 1,2,3 or 4 wt% between 10 and 35℃ at shear rates from 1.7 to 1020 s^(-1).Rheological modeling indicated that a power law pseudoplastic model was the best fit for the experimental data,giving a regression coefficient of *** addition of these inhibitors induced Newtonian fluid behavior in the crude samples such that the shear stress-shear rate relationship plots were linear at all *** optimum concentrations of the inhibitors in this study were 2000 ppm PEB(providing a 33% viscosity reduction)and 1 wt% nano ZnO(providing a 26% viscosity reduction).A combination of these additives at these concentrations provided a synergistic effect and gave a greater viscosity reduction of 41%.This work demonstrates that a blend of ZnO nanoparticles and PEB can improve the flowability of waxy crude.
