| 摘 要： | 在地震反演过程中,子波质量至关重要,它将直接影响着最终的反演结果。这里详细地讨论了Strata地震反演系统中提取子波的几种常用方法,并对它们的特点做了简要分析。最后,提出了一种新的提取子波方法,利用反演误差对子波进行相位校正,使误差图上的相关能量尽可能达到最小,用校正后的最佳子波进行地震反演,在淮南张集煤矿西三采区地震反演中,获得了满意的地质效果。

| Abstract: | In the process of seismic inversion, the wavelet plays a vitally important role, which will directly influence the final inversion quality. This paper gives an in-depth introduction of the common wavelet-extracting methods in the Strata inversion system, and conducts a brief analysis on their own characteristics. Finally, a new way of extracting wavelets has been proposed which is trying to reduce the correlation energy in error charts by editing the phase of wavelets. And satisfying geologic effects have b... |
