Abstract:

The lateral prediction becomes more difficult because of the strong heterogeneity of carbonate reservoir. A measurement is presented in this paper, which determines seismic response of reservoir by horizon calibration of two-step method and seismic interpretation, predicts the distribution characters of carbonate reservoir with analysing many different kinds of seismic characters including amplitude,frequency, signal-to-noise ratio, and especially waveform, and delineates favorable reservoir zones inTazhong A area.
