摘要
In the research context of preliminary evaluation on source rock of the northeast sag, which is the new exploration area in South Yellow Sea basin at present, this paper tries to trace the main formation and dimensional distribution of major source rocks in northeast sag based on the seismic reflection characteristics. The method of seismic attribution is applied for the first time to the prediction of the thickness of major source rocks (Upper Cretaceous Taizhou formation and Palaeocene Funing Formation) in northeast sag, which is tested by the method of seismic velocity-lithology prediction to estimate the thickness of Taizhou Formation source rock. The authors suggest that Taizhou Formation source rock is widespread with larger thickness in northeast sag than Funing Formation, and the west sub-sag in northeast sag is the optimum hydrocarbon-generating sag.
