At present，reservoir architecture characterization is the most commonly used and effective method to describe a single sand body in fine reservoir description. At the same time，different reservoir architecture interfaces have a significant impact on the remaining oil distribution within the reservoir. Based on detailed literature research and analysis，the similarities and differences in reservoir architecture characterization between China and other countries were identified from the aspects of research contents，research objects，and research methods related to reservoir architecture. It was proposed that the problems existing in the research on reservoir architecture in China were mainly reflected in the following aspects：The classification scheme of reservoir architecture is not uniform；the classification level is too fine；the research focuses on conceptual innovation rather than the application of results；the research of reservoir architecture interface has not attracted enough attention，and the characterization method of reservoir architectures is relatively single. The future development direction of reservoir architecture research in fine reservoir description were pointed out：the application of quantitative characterization methods of reservoir architecture such as well-seismic combination，the study of architectures of special lithologic reservoirs such as carbonate rocks，the establishment of classification scheme of characteristic reservoir architecture，the characterization and application of reservoir architecture interface，and the field application of reservoir architecture characterization results.
