Realizing migration imaging with multiples is a dream of seismic exploration. The research group under the guidance of Liu Yike and Chang Xu, professors of Institute of Geology and Geophysics, Chinese Academy of Sciences, proposed a novel seismic migration imaging approach denoted as reverse time migration of multiples to come true the dream. The group explains the physical meaning of multiple imaging, and offers a mathematical proof using migration of multiples. A numerical example applied to Sigsbee2B demonstrates the approach is valid for subsalt imaging, and the imaging results are very promising. It would be available for the complex structures such as rugged sea bottom and complicated tectonic pattern imaging. The academic circles of seismic exploration and industrial fields set a high value on the approach.
