Chemical flooding in tertiary oil recovery is the main method to increase and stabilize crude oil production in China. The development of chemical flooding is inseparable from the construction，innovation and precipitation of standardization work. In order to systematically summarize the current situation of chemical flooding technical standards in China，promote the deep integration of chemical flooding technical standards innovation and standardization construction，and lead the high-quality development，this paper analyzed the framework and content of chemical flooding technical standards，as well as the comparison of domestic and foreign technical standards and the differences of key indicators. The results showed that there were many traditional chemical flooding standards in China，such as polymer flooding and composite flooding，but lack of standard supply in emerging fields such as nano flooding and foam flooding. The evaluation system of chemical flooding technical standards in China were more perfect than that of foreign standards. Finally，the improvement and development direction of chemical flooding technical standards in China were proposed.
