【摘要】 针对常规提高地震数据分辨率处理技术难以满足储层反演、烃类检测的要求,将希尔伯特-黄变换(HHT)方法引入地震数据处理中,提出了一种新的振幅频率恢复方法。应用结果表明,采用HHT振幅频率恢复技术处理后的三维地震数据分辨率有明显提高;在二维地震数据处理中不但分辨率大大提高,而且保持了地震数据的相对振幅关系,具有良好的保真性。更多还原

【Abstract】 The traditional processing techniques to improve seismic resolution can not meet the requirements of reservoir inversion and hydrocarbon detection,and a new technique of amplitude and frequency restoration is developed by introducing Hilbert-Huang transformation(HHT) into seismic processing.Its application has shown that the resolution of 3D seismic data processed by this technique is significantly improved,and that in 2D seismic processing,not only the resolution is improved,but also the relative amplitude relationships of seismic data are maintained,resulting in a good fidelity.更多还原
