Enhanced oil recovery（EOR）chemicals play a key role in increasing oilfield production and extracting residual oil resources. However，their effectiveness and reliability depend on a series of technical and quality standards. The development trends and compilation process of evaluation standards for EOR chemical agents and the characteristics of current standards for EOR chemical agents domestic and abroad were focused and summarized，the characteristics of these types of chemical agents，and suggestions for future development trends and evaluation standards were analyzed as well. The proposal is to provide a reference and basis for the development direction of standards for chemical agents used for EOR to meet the constantly changing industry needs. By standardizing the quality and performance of these chemicals，their effective application in oilfields can be ensured， thereby increasing oilfield production capacity and reducing potential environmental and economic risks. In the constantly evolving oil and gas industry，standardization will continue to play a key role in providing support and guidance for the industry’s sustainable development.
