摘要:
当前海洋地震资料处理中能量引起的采集脚印难以有效压制,严重影响了目标区信噪比和分辨率。针对能量引起的采集脚印,开发了基于克里金算法的采集脚印衰减新技术。基本思路是应用克里金算法统计地震数据体的空间相关变化量,求取去除采集脚印系数体,达到去除能量采集脚印的目的;关键在于将区域化模型视作为采集脚印噪声因子和有效反射信号组成的,地震数据体每个采集脚印因子有对应的变差函数,利用采集脚印和地震有效反射信号在变差域的差异性即可实现采集脚印的预测和衰减。在海洋地震资料处理中应用结果表明:该方法完全数据驱动,采集脚印衰减效果明显优于传统类方法,同时对有效反射保护较好;为采集脚印衰减提供了一套新的解决方案,具有较好的推广应用价值。
Abstract:
In current marine seismic data processing, acquisition footprints caused by energy variations are difficult to be suppressed effectively, severely impacting the signal-to-noise ratio and resolution of target areas. This paper focused on energy-induced acquisition footprints and developed a novel acquisition footprint attenuation technology based on the Kriging algorithm. The core idea of this method is to apply the Kriging algorithm to statistically analyze the spatial correlation variations in seismic data volumes,thereby deriving a coefficient volume for removing acquisition footprints and achieving their suppression. The key innovation lies in modeling the regionalized seismic data as a combination of acquisition footprint noise factors and effective reflection signals. Each acquisition footprint factor of the data volume corresponds to a specific variogram, and the distinction between acquisition footprints and effective reflection signals in the variogram domain enables the prediction and attenuation of footprints. Application results in marine seismic data processing demonstrate that this fully data-driven method outperforms traditional approaches in footprint attenuation while better preserving effective reflections. It provides a new solution for acquisition footprint attenuation and holds significant potential for broader application.
