The fine characterization of channel sand body is a complex system engineering. The longitudinal superposition relationship of channel is complex, the sandstone thickness is thin, and the lateral changes of lithology and physical properties are obvious. It is necessary to carry out the research on the integration of processing and interpretation and seismic geology. The key technologies of seismic high-resolution pre stack and post stack inversion of medium and shallow channel sand bodies with “improved HHT point spectrum whitening” and “weak sidelobe wavelet structure” as the core and “azimuth well control inversion modeling” and “Cauchy regularization high-resolution inversion” as the core have been formed through experimental research.
Key words: Channel sand / seismic high-resolution imaging processing / pre stack inversion / post stack inversion
