Abstract：Channel sands were extensively developed in the Late Miocene Huangliu Formation and the Pliocene Yinggehai Formation, Yinggehai Basin.Our challenges were to look for favorable channel sand bodies and predict gas-bearing traps.In this paper, two new channel seismic faces styles in the Yinggehai Basin have been analyzed：one is a weakly continuous event with weak amplitude between two strongly continuous event with strong amplitude, and the other is an inverted seismic facies of convex channels.The former belongs to channel sands.The latter is caused by differential compactions of sandstone and mudstone.Gas-bearing channels in the area are predicted by seismic forward modeling and AVO crossplot.The predictions show very good match with the actual drilling resutt, and demonstrate the efficiency of this method.
