     Taking the 2na Member of Shahejie Formation in the Yellow River Mouth sag as an example, geological models were built depending on the 90° phasing of seismic data and the geologic setting. The modeling synthesis records from 0~-phase to 90°-phase were used to make the geological models more precise. Then according to the attributive character obtained from the 90°-phase of seismic data, seismic attributions extraction and formation slices could be used to predict the distribution of the sandstone. The results indicate that the geological models can be directly perceived through the 90°-phase seismic data, and at the same time the trough of waves can not only correspond to the sand body but also show the outline of the sand belt which is spreading in the seismic modeling synthesis of 90° phasing. What＇ s more, the ichnography from the seismic attribution extraction about the character of trough amplitude can clearly show the contour profiles and boundaries of the sandstone.
