Thinking on Hydrocarbon Accumulation in Architecture of Eocene Deep Strata,Central Anticline Belt of Xihu Sag,East China Sea

The exploration prospect of deep layer in the central anticline in Xihu sag is inestimable.However,the geology study in this area is still not enough for a long time.On the basis of the interpretation results of continuous 3D seismic data,analysis on structure,stratigraphy and hydrocarbon accumulation has been done for the deep layer in the middle area of depression (cross Well Yuquan-1),and prediction has been made for hydrocarbon exploration in deep layer in the central anticline in Xihu depression.
