地震数据面波衰减性能定量评价
|
摘要
目前地震数据中面波衰减处理结果的评价还没有定量标准,仅通过观察对比面波衰减前后的地震剖面和频谱来进行主观、定性评价。在总结面波滤除处理性能要求的基础上,提出了地震记录中面波道和反射道的概念,分析了反射道数据误差和面波道数据自相关的性能特点,定义了面波衰减比作为评价面波衰减性能的客观定量指标。研究结果表明,所提出的以面波衰减比的平均值作为定量评价标准是有效的。
Up to now,there was no quantitative evaluation criterion for surface wave attenuation performance in seismic data.The surface wave attenuation performance was qualitatively evaluated by subjectively observing the seismic data and by comparing the spectrum of the original and processed data.The concept of surface wave trace and reflection trace was proposed and the features of reflection wave error and surface wave autocorrelation were analyzed based on summing up the requirements of filtering performance.Then the surface wave attenuation ratio(SWAR)was defined,which was used as a subjective and quantitative index for evaluating the surface wave attenuation performance.Experimental results demonstrate that the proposed average SWAR is effective for quantitative evaluation criteria for evaluating surface wave attenuation performance.
