Nano-emulsion:properties,preparation and application progress in unconventional oil and gas development
The characteristics and differences of nano-emulsion and microemulsion are reviewed in detail from the aspects of size,preparation method,thermodynamics and kinetic stability,and the main factors af-fecting the stability of nano-emulsion and the instability mechanism are analyzed in detail.The preparation method,oil displacement and drainage mechanism of nano-emulsion are systematically introduced,and its influencing factors are summarized,and the application status of nano-emulsion in the development of un-conventional oil and gas reservoirs is reviewed.The development of new low-cost and efficient preparation methods and the study of new temperature-resistant and salt-tolerant nano-emulsion are the main research directions in the next step.
