Abstract：Reverse time migration (RTM) is the most accurate migration method at the moment.We discuss in this paper RTM development strategy,key effectors affecting RTM and corresponding solutions based on some aspects such as RTM algorithms for anisotropic media,physical modeling,data preprocessing,velocity and anisotropic parameter modeling,imaging noise processing and amplitude preservation,and the relationship between full waveform inversion (FWI) and RTM.Then we point out the future development trend and research emphasis of RTM.Finally we consider that RTM research based on full waveform inversion may be an important direction for the future.
