摘要:

沉积岩地区,总是以-种独特的地震响应为特征的。从地震反射中可以提取相应的地层和岩性信息。本文根据地震反射波的振幅信息,频率信息及波形信息的组合关系,提出了以微地震相分析方法来预测地层的岩性,从宏观上来说明岩相的变化规律,最终结合地质手段来达到划分和描述沉积相的目的。实例表明此方法是可行性。

Abstract: Sedimentary rock layers are always characterized by a particular seismic response. Therefore, the lithological information can be gained from seismic reflection waves. According to the combination relationship between amplitude,frequency and wave shape of seismic reflection waves,the lithologic characteristic can be predicted by means of microseismic facies analysis and the law of lithofacies change can be explained from a macroscopic angle. Therefore the purpose to divide and describe the sedimentary facies can be achieved by geological method. The examples show that this method is quite feasible.
