Since the seismic sedimentology was born, the studies that lots of scholars did were mainly focusing on the seismic geomorphology. On the contrary, there were few scholars who studied on the seismic lithology. In the past, the technologies of seismic lithology was mainly 90° phase rotation and post-stack inversion, but both of the methods exist some defects when applied to complex areas. The concept named seismic lithology volume has been proposed in early study: it converts seismic data to seismic attribute volume with a clear lithologic significance, and used to characterize the seismic geomorphology. In this article, we restart to derive the expression of AVO attributes and choose the new G-attributes as the seismic lithology volume, and then successfully applied in the middle of Sichuan Basin.
