摘要
Seismic amplitude spectrum gradient presents a rate of reflection amplitude versus frequency in the effective band, which highlights variation of seismic data amplitude with different frequency. So it reveals variation of reservoir permeability. The paper discusses computations of amplitude spectrum gradient and its applications for prediction of plane distribution of high-permeability sandstones in WC exploration project. The results show that this approach successfully predicts lithologic traps and structural-lithological compound traps and delineates a series of potential areas.
