Seismic inversion for reservoir prediction in the west of Liaohe tidal zone

As the exploration targets are increasingly complicated in the west of the Liaohe tidal zone,the reservoir prediction becomes more and more important.In this paper,we mainly illustrated the key techniques of seismic impedance inversion and analyze the inversion effects in the west of Liaohe tidal zone.And then,based on the result of the seismic impedance inversion,we predicted the thickness and the content of sandstone quantitatively and analyzed the lateral distribution of reservoir.Finally,we predicted the favorable zone,which provided a good foundation for identifying lithology traps.
