摘要
时频分析技术是一项十分有效和直观的地震资料特殊解释技术,它通过一定的处理方法,把时间域的数据转换为频率域时频数据,时频分析在地质勘探中具有广泛的应用,表现在地层旋回性方面,它可以实现对不同类型沉积旋回的研究、层序界面的追踪和对比以及不同规模沉积旋回的研究。
The Time-Frequency analysis technique is a very effective and intuitional technique in the explanation of seismic data. Converting the data from time domain into frequency domain with a special method, it is widely used in geological exploration. In the research of strata cyclicity, it can be used in the study on different types and scale of sedimentary cycle and the tracing of stratigraphic interface.
