The Research on Imaging Condition of Reverse Time Migration

At the beginning of this century,the increasing demands for high performance computing(HPC) and the rapid development of computing technique,lead to advances and applications of reverse time migration.However,in order to resolve the existing problems of reverse time migration such as low frequency noise,domain optimization to improve imaging conditions imaging method will be applicable;Further more,it is also significant to choose appropriate imaging condition to realize the true amplitude in reverse migration.According to different imaging purpose,using the reverse time migration to analyse the conditions is equally notable.This study gives five kinds of imaging conditions of reverse time migration,further interpretation in noise and amplitude areas of various methods has been discussed,ultimately,the analysis shows that the reverse time migration provide comparison and recommendations for the future application.
