| 摘 要： | 分频解释技术可以刻画碳酸盐岩储层中缝洞发育所引起的地震反射频率特征。将分频解释技术应用于碳酸盐岩缝洞储层的地震反射波分析，通过分析由分频技术生成的调谐体和离散频率能量体的变化特征，可以确定充填流体或气体的孔洞储层引起的地震反射波振幅和频率的变化异常。实际工区的地震资料分频解释结果与钻井结果一致，说明利用分频解释技术得到的时频谱可以反映地下碳酸盐岩储层的位置和基本形态。

| Abstract: | Spectral decomposition technique can depict the frequency characters of seismic reflection that are caused by carbonate reservoirs.We used spectral decomposition technique to analyze the seismic reflection waves in carbonate rocks of fractures and caverns.The variations of reflection amplitude and frequency caused by fluid in the fractures and caverns were determined through the analysis of harmonic cube and discrete frequency energy cube,and were used to predict the hydrocarbon-bearing potentials.The predicted results are in agreement with the drillings,which indicates the feasibility of the proposed method. |
