The effect of additives of single-wall and multi-wall carbon nanotubes on the rheological characteristics of inverse emulsions

In this study, the rheology of inverse emulsions based on mineral oil modified with single-walled carbon nanotubes (SWCNTs) was studied and compared with the results of the influence of multi-walled carbon nanotubes (MWCNTs) additives. The mass concentration of SWCNTs in emulsions varied from 0.01 to 0.1 wt%. Dependences of rheological characteristics on SWCNT concentration were obtained. Based on the results of the study, it was shown that nanotube additives can significantly change the rheological characteristics of emulsions. The use of SWCNTs to improve the rheology of drilling emulsions is several times more efficient than MWCNTs and hundreds of times more effective than additives of spherical nanoparticles.
