Nano-technology has obvious advantages in description of oil and gas reservoir characteristics, detection of formation, analysis of fluid properties and enhanced oil recovery. It can be used to acquire some parameters like formation temperature and pressure as well as types of fluids, identify formation characteristics and remaining oil, and improve efficiency and performance of oil and gas exploration, development and production. The study of reservoir nano-technology is drawing extensive attention at present time. Oil companies, service companies, research institutes and universities have made studies in this area. Based on application and development targets of reservoir nano-technology, this paper is focused on the latest development in application of reservoir nano-technology, such as electronic sensors, powerless sensors, contrast agents, self-sensing cement, fluid-repelling coating, nano encapsulation, and nanoparticle surfactant.
