Application of seismic wave absorption and attenuation technology in predicting fracture-vug carbonate reservoir

Based on excellent localization property in time domain and frequency domain for non-orthogonal wavelet transform, time-frequency analysis method of the non-orthogonal Gabor-Morlet transform was brought to seismic wave absorption and attenuation analysis, it is stated in this paper that when seismic wave propagates through oil & gas reservoirs, the high frequency component will be absorbed, thus the high frequency energy will rapidly attenuate. By applying the theoretical characteristics the prediction was conducted for the fracture-vug carbonate reservoir in TZ45 well zone, the related results show that the prediction is successful and excellent, matching the drilling results. In this paper it is demonstrated that seismic wave absorption and attenuation technology is an effective mean to predict the fracture-vug carbonate reservoir.
