The conventional internal multiples elimination method can not be applied in the OBC data because receivers are at the bottom while the sources are at the surface of the sea��which makes the practical marine seismic data processing face with great challenge�� In this paper��we get the virtual shot records with the virtual source and receivers at the bottom of the sea by reconstructing the OBC data��using seismic interferometry�� The results are the same as conventional seismic data with the source and receivers at surface��which can convert the internal multiples of the OBC data to conventional surface-related multiples and internal multiples�� Comparing with the results of CFP method��we can conclude that the seismic interferometry wave-filed reconstruction method can be applied well in in- ternal multiples elimination of OBC data��
