eservoirs delineation. This paper mainly discusses the broadband high-density seismic data processing techniques, including frequency- and time-dependent pre-stack amplitude-preserved noise attenuation, well- and horizon-controlled amplitude compensation, target-controlled resolution enhancement processing, and iterated geologic-constrained velocity analysis and high-precision residual static corrections. Final processing results are characterized in high-resolution and abundant geologic information,and easy for identification of sandstone, pinch-out structures, stratigraphic unconformities, and delineation of faults and lithologies features. Attributes of coherence cube clearly reveal spatial distributions of faults, and curvature attributes distinctly depict minor faults. All information indicates that the broadband high-density seismic data processing results are capable to perform lithologic reservoir interpretation.
