Abstract：The application and characteristics of CO2 flooding in the USA were analyzed and summarized. Complementary techniques of CO2 flooding were generalized by an application example, and then the enlightenment was expounded for CO2 flooding in China. The development process and forming reasons of CO2 flooding technology were analyzed and summarized based on the systematic tracking of EOR survey data all over the world and the sufficient investigation of CO2-EOR technology application. The current situation of American CO2-EOR technology was evaluated using the quantity, scale and EOR production of projects as indexes. The characteristics and development-driving force of the projects were summed up. The characteristics of American CO2 miscible flooding were emphatically outlined about reservoir properties, crude oil properties and project timings. Meanwhile, the scale and reservoir adaptability differences between American CO2 miscible and immiscible flooding were comparatively analyzed. A series of complementary techniques were illuminated with the development of SACROC CO2-EOR project as an example. The challenges, technical bottlenecks and suggestions were analyzed and proposed for the promotion of CO2 miscible flooding technology in China.
