摘要
随着对地震资料精细解释的深入,采集脚印对时间切片、各种属性等的影响越来越引起人们的重视.国内关于采集脚印的研究刚刚起步,本文分析总结了采集脚印产生原因,归纳了采集脚印计算的方法和工具,详细讨论了在资料处理过程中,包括叠前、DMO和叠前偏移、叠后三个方面压制和衰减采集脚印的方法,这些方法明显地提高了数据体的信噪比和可信度.
With the development of elaborate seismic interpretation, people pay more attention to the effect of acquisition footprint on time-slice and seismic attributes. The study of acquisition footprint is not enough in China. This paper analyzes and summarizes the causation and the calculation method of acquisition footprint, and discusses detailedly the suppressing and attenuating methods at pre-stack,DMO,migration and post-stack. Those methods apparently improve the S/N and credibility of seismic data.
