Seismic Reservoir Prediction and Hydrocarbon Detection without Well for Structure A in the North Yellow Sea Basin

The North Yellow Sea Basin is one of petroliferous basins where the exploration and study degree is low in east China.Beginning with analysis of original data in the study area,using special treatment methods of seismic data such as the impedance,instantaneous amplitude,instantaneous frequency,etc.,as well as other AVO oil and gas examination technology,combined with regional sediment and geological data,this paper generally analyzes the reservoir,seal distribution,and oil and gas geological conditions of Structure A in the central depression of the North Yellow Sea Basin.It is concluded that there are two sets of advantageous reservoir and seal compounding in the area,and the oil and gas condition at the center and limb of the Structure is better.These results have an important guiding sense for study of the petroleum trap distribution in the research area.
