Abstract:  Combined with the petroleum engineering demands by oil and gas exploration and development, the nanotechnology and their advantages in petroleum engineering are summarized, the research progress and application of nanotechnology in drilling and completion, reservoir description and stimulation, EOR are analyzed, and the application and development prospects of nanotechnology in the future are discussed in this paper. Nanotechnology has played an important role in drilling and completion fluid, its application in reservoir description, stimulation, and EOR is still in the laboratory stage. Cost, stability, transportability in rocks, production and modification,are the key problems for large scale oilfield application. The future development trends of nanotechnology lie in the four aspects, improving drilling and completion fluid performance, improving tools and materials performance, improving reservoir description accuracy, and improving oil and gas production.

Key words:  nanotechnology, additives, reservoir description, enhanced oil rate( EOR), development trend
