“…Since its first introduction in 1998 (Zeng et al, 1998), the concept has been applied in the identification of paleorivers, the sedimentary facies and sedimentary environment evolutions of carbonate platform and the slope fans with many good results (Carter, 2003;Chen.& Meng, 2004;Crumeyrolle et al, 2007;Darmad et al, 2007;Gee & Gawthorpe, 2007;Handford & Baria, 2007;Ling et al, 2005;Lin et al, 126 2007;Liu, B.G. & Liu, L.H., 2008;Nordfjord et al, 2005;Posamentier & Killa, 2003;Prather, 2003;Sullivan et al, 2007;Schwab et al, 2007;Wang et al , 2004;Wu et al, 2005;Zeng et al, 2003Zeng et al, , 2004Zeng et al, , 2007Zhang et al, 2007), but rarely used to study nearshore subaqueous fans. In this paper, we took the nearshore subaqueous fan in the Dongying Depression as a case, and used the pseudo-acoustic 3D seismic inversion method on characteristic logs to reconstruct 3D seismic sedimentological structures of the nearshore subaqueous fans including the distribution of the effective sand-conglomerate reservoirs and the temporospatial evolution of individual nearshore subaqueous fan system.…”
