浊积岩油气藏勘探是目前油气储量与产量增长的重要途经，而对浊积岩的识别和储层预测却是现阶段这类油气藏勘探的主要技术瓶颈。文中以地震沉积学为指导，综合应用时频三原色、年代地层切片、属性投影及相控储层预测等技术，进行浊积扇体识别及储层地震描述，从而摸索出一套适合辽东湾地区浊积岩体储层刻画的地球物理技术流程，这一方法对指导该区的岩性油气藏勘探具有一定的推广应用价值。

The exploration of turbidite reservoirs has already played an important role in the output growth of oil and gas, but to identify the turbidite and predict the reservoir is the main technical bottleneck in the exploration of this kind reservoir at present. 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 seismic 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.
