    APPLICATION OF PRE-STACK SEISMIC ATTRIBUTES IN FLUVIAL RESERVOIR PREDICTION-TAKING THE XINBEI OILFIELD AS AN EXAMPLE

    • It remained a question if the strong reflection of seismic data in Xinbei oilfield is an effective reservoir.Detailed velocity analysis and amplitude-preserved pre-stack processing for time migration were carried out for higher energy,higher SNR,smaller offset for nearer and distant gathers and better isophase coincidence in the fluvial reservoir in Xinbei oilfield.According to the stratigraphic architecture and fluid information from different angle gathers,we used the amplitude difference between nearer and distant offset gathers in the sandstone of the unit 4 of the upper member of Guantao Formation.Results show that the method is effective in prediction of hydrocarbon potential in the reservoirs.
