基于希尔伯特—黄变换的地震资料高分辨率处理

The Marine Seismic Data High Resolution Processing Based on Hilbert—Huang Transform

常规提高地震资料分辨率处理技术不能更好地满足实际生产需求。本文将希尔伯特—黄变换引入到地震数据处理中,提出一种新的地震资料高分辨率处理方法。MarmousiⅡ和实际地震数据处理结果表明,与反褶积、反Q滤波等常规高分辨率处理方法相比,希尔伯特—黄变换不仅能够有效提高地震数据的分辨率,而且较好地保持了地震数据的相对振幅关系,可以为后续的地震反演、储层预测、烃类检测和地震属性分析等奠定良好基础。

The traditional seismic data high resolution processing technology can not meet the requirements of real production,so a new high resolution processing technology based on Hilbert-Huang transform is introduced in the paper.The processing results of MarmousiⅡ model and real seismic data confirm the effectiveness of proposed method,and show that this method can not only improve seismic data resolution effectively but also preserve well the relative vibrating relationship of seismic data compared with conventional processing technology such as Qcompensation and deconvolution.This results processed by Hilbert-Huang transform can be applied to seismic inversion,reservoir prediction,hydrocarbon detection and seismic attributes analysis.
