ARGIN: 0cm 0cm 0pt" class=MsoNormal>ang=EN-US>The carbonate vuggy reservoirs in the study area show obvious “string beads” reflection in seismic profile and star or massive feature in plane map of seismic attributes. The hydrocarbon-bearing vugs are characterized by low gamma ray and low velocity from geophysical analysis. The hydrocarbon-bearing property is identified by pseudo-acoustic impedance inversion using the method for reconstruction of acoustic velocity curve from gamma ray curve. Combination of this method with seismic attribute technique can more precisely predict the distribution of oil-gas reservoirs.amespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
