Nano-materials could improve cementing qualities and wellbore integrity through improving the strength and toughness of cement stone when they were applied in well cementing slurries. The domestic and international research progress of nano-materials applied in cementing were introduced，including nano-silica，nano-sized iron oxide，modified carbon nanotube， multiwalled carbon nanotube， nano-sized clay and other nano-materials. The existing problems and developing directions of the application of nano-materials in cementing were discussed. The discussion results had reference value for further application and research of nano-materials in the field of cementing.
