Experimental study on the synergistic effect of nano-fluids and amphoteric surfactants to improve drilling fluid properties
In this paper,the effects of silicon carbide nanofluids and surfactants on the physical and chemical properties(thermal stability,viscosity,surface tension,and filtration characteristics)of water-based drilling fluids were investigated.A surfactant silicon carbide(SiC)drilling fluid was formed by mixing silicon carbide nanofluid,surfactant solution,and water-based drilling fluid.The viscosity,surface tension,and filtration properties of the mixed drilling fluid were studied using the rheometer,the tension meter,and the filter press,respectively.The experimental results showed that the amphoteric surfactant has the greatest increase in drilling fluid viscosity compared with conventional surfactants.In addition,the mixed drilling fluid has better thermal stability.With the increase of temperature,the average change rate of viscosity is 9％,and the surface tension and filtration rate decrease by 31.0％and 22.2％,respectively.
