The Effect of Nanoparticles Addition on the Properties of Polymer Weighted Drilling Fluid

Abstract

The experimental studies of polymer drilling fluid s weighted with B-5 and B-6 barite with the addition of silicon oxide nanoparticles wt. 2% are presented. The concentration of barite particles in muds ranged from 10 to 40 wt. %. The size of microparticles was 70 μm. The size of nanoparticles was 5 nm. The effect of nanoparticles addition on rheological and tribological parameters of polymer drilling fluids weighted with barite depending on the concentration of microparticles was established.
