| 英文摘要 | Time-lapse seismic exploration, as an effective means of reservoir dynamic monitoring, plays a vital role in obtaining subsurface media variation. Misleading travel -time differences will occur due to differences in environmental conditions, acquisition methods, and processing techniques between multiple periods of seismic data. To eliminate the travel -time discrepancy, we introduce the Dynamic Time Warping (DTW) method to realize the optimal matching of seismic angle gathers. Based on the effective variation information of different period seismic records, we propose time-lapse seismic difference inversion by elastic wave equation via scattering theory to yield the difference in elastic parameters of the formation and realize quantitative characterization of reservoir alteration. Our method adopts WKBJ approximates the inhomogeneous background, which has higher inversion accuracy, especially under complex geological conditions. Here, we carried out numerical simulation experiments and practical data applications on the proposed method, which proved that the proposed method allows for higher resolution inversion results and more precision characterization of stratigraphic changes than traditional methods. |
