Abstract：The paper introduced the application ofSeis-mic phase techniqueto recognize delta, turbiditevolume and meandering river inBohai Baypractical cases. In practical application, marea byaccord-ance with exploration and development targets inBohai Bay area, we used artificial neural networkand primary compositional analysis(PCA)tech-niques to carry out recognition and category of thewaveform-various feature of seismic traces and re-fleeted geologic feature in studied area, obtainingseismic phase map, and in combination with drilleddata and geologic data to carry out correction andintegrative analysis, obtaining sedimentary faciesrelative to seismic phase and further dividing reser-voir fades zone of interest, which provided basisfor implementing next exploration and develop-ment in the studied area.
