In this paper, the technologies of time-frequency three primary colors, chronostatigraphy slicing, attribute projection and facies- constrained reservoir prediction are used to identify the turbidity sand body and describe the seismic reservoir based on seismie sedimentology. It presents a set of geophysical methods suitable for the turbidity reservoir description in Liaodong Bay Area, Bohai Basin. This method has certain application value for the stratigraphic-lithologic reservoir exploration in this area.
