Abstract

This paper presents the results of experimental studying the effect of single-wall carbon nanotube (SWCNT) additives on the viscoelastic and thermophysical properties of hydrocarbon-based drilling fluids. The rheology, viscoelastic properties, thermal conductivity and thermal diffusivity of SWCNT-modified drilling fluids with different hydrocarbon phase contents have, for the first time, been investigated. The work has shown that the addition of SWCNTs can significantly improve the functional properties of hydrocarbon-based drilling fluids. The introduction of the nanotubes into a drilling fluid can, in a number of cases, increase the apparent viscosity by an order of magnitude, enhance the consistency parameter and yield point values by many times, and almost double the thermal conductivity, thereby opening up broad prospects for using single-wall nanotubes as regulators of drilling fluid properties.
