摘要
地震资料处理技术和流程多以构造成像为重点,而忽略了处理方法及参数变化对地震波振幅的改造,影响了处理结果的保幅性。基于模型数据和实际资料,对面波压制、几何扩散补偿、预测反褶积等几项关键处理技术的保幅性进行了分析,提出了提高保幅性的处理思路和流程。处理结果表明,采用合理的方法和流程,使面波压制、几何扩散补偿等处理环节的相对保幅性得到了明显提高。
The requirement for relative amplitude preservation of seismic data has become higher and higher. However, the techniques and procedures of seismic processing are mainly focused on structure imaging, but their effects on amplitude are often ignored, so the processing results are often badly amplitude-preserved. Based on real and model data, this paper has analyzed the characteristics of am- plitude preservation of surface wave suppression, geometrical spread compensation and predictive deconvolution techniques. On the ba- sis of amplitude-preservation analysis, the optimized processing methods and procedures are proposed. The analytical result shows that the amplitude features of seismic processing results can be preserved better.
