摘    要:三维高分辨处理就是要拓宽有效信号的频带,并使地震数据在宽频带内有较高的信噪比。基于这一观点,进行了大量的分析、试验,设计了一套以叠前反褶积组合、大值干扰自动压制、高精度速度分析、地表一致性处理、三维DMO及叠后方向约束去噪、F-X域地震道内插、三维一步法偏移等处理方法为主的三维高分辨地震资料处理框架。通过实际资料处理表明,三维高分辨处理后的剖面比常规处理的剖面主频提高1倍以上,并且断层归位准确,信噪比较高。

关 键 词:高分辨率  信噪比  振幅补偿  反褶积  频带

Abstract:The method is to broaden the frequency band of effective signals and raise the signal -to -noise ratio in wide frequency band. According to the method and large amount of ana1ysis and experiment, a processing procedure is dcsigned which consistS of prestack deconvolution conbination, automatic restraining interferencc of large irnplitude, velocity analysis with high accuracy- etc. Through utili7ation of this method, the processcd data show that thc dominant frequency is doublcd .Comparcd with conventional processing method,fault position is accurate and the signal - to - noise ratio higher.
Keywords:High resolution  Signal/noise ratio  Amplitude compensation  Deconvolution  Frequency band
