The application of nanotechnology in drilling fluids has been a research hotspot recently in oilfield chemistry.With the in-depth study of the lubrication effect of nanoparticles,they have been used for lubrication modification of drilling fluids.The amount of nanoparticles used in drilling fluids is small,and the potential negative impact on the environment is weak.The development of new environmentally friendly nanolubricants for water-based drilling fluids is the current trend.This paper analyzes application trends of nanolubricants used in drilling fluids,including the anti-wear and friction-reduction mechanism,types and application forms of nanoparticles,and the lubricating effects.The problems in the application of nanolubricants in drilling fluids are elaborated,with a focus on exploring the progress of surface modification of nanolubricants.At the end,a brief prospect for the synergistic and simultaneous development of multiple effects is given.
