Abstract：The 2-D geologic model was constructed based on the practically drilled stratigraphic sequence and measured velocity and density data at Pai-2 well, from which the forward simulation was conducted. The resulted forward simulation was correlated with practical seismic data, and both of them had similar feature of seismic response to the sand body in Shawan Formation reservoir at Pai-2 well:the oil-bearing sand body on the higher parts showed strong reflection energy, all rapidly energy-changed points appeared when seismic reflection events stretched toward lower parts, and reflection energy changed from strong to weak until disappearing in these changed points. The frequencies related to oil layer and water layer also have distinctive difference:lower for oil layer and higher for water layer. Combing application of amplitude with frequency parameters can successfully predict the reservoir in Shawan Formation first oil-sand layer in Chepaizi area.
