Emulsification is one of the important mechanisms in chemical flooding, which is widely studied in recent years. In addition, the new technology of emulsification displacement is focused increasingly. The basic concepts in emulsification have been introduced. The emulsification mechanism in chemical flooding has been summarized, and the influencing factors in chemical flooding emulsification has been analyzed. The current research status of new technology for emulsification displacement has been introduced. Some problems are pointed out and some suggestions are given. As the application of chemical flooding gradually becomes in a larger scale, the demand for new chemical flooding technology is increasingly strong. The deep study of emulsification should go on. The technology of emulsification displacement has great research value and application potential.
