  • To understand the factors affecting the dispersibility of the carbon nanotubes (CNTs) in cement slurries containing no dispersants, the CNTs was amide-modified on its surface and the modification was characterized by IR. The dispersibility of CNTs was evaluated through the electro-conductivity difference in different zones of set cement, and the effects of the amidated CNTs on the mechanical property and the overall performance of the set cement were also evaluated. The studies showed that dispersant for CNTs (gum Arabic) at high concentrations rendered negative effects on the retardation and settling properties of cement slurries, reducing the strength of the set cement by 51.4% and the density difference between the top and the bottom of a cement column was as high as 1.309 g/cm3. Amidated CNTs can be evenly dispersed in a cement slurry with no dispersant. CNTs after amidation had its spatial conductivity variance reduced by at least 1000 times. The amidated CNTs had stronger water wettability. A cement slurry treated with 0.06% amidated CNTs had its compressive strength, rupture strength, tensile strength and impact resistance increased by 33%, 30%, 61% and 33%, respectively. The amidated CNTs had no effect on the thickening, free water and filtration rate of cement slurries. It reduced the permeability and porosity of a set cement by 22.9% and 25.5% respectively. It was concluded that in cement slurries with no dispersants, the amidated CNTs can be evenly dispersed and can improve the mechanical performance of the cement slurries. This property renders the amidated CNTs application prospects in well cementing.
