摘要
反褶积技术能提高有效波高频成分，但也放大了高频噪声、降低了信噪比，甚至有时使反褶积提升的高频成分被噪声淹没，达不到提高分辨率的目的。本文利用对地震波有效功率谱修整的方法进行常规反褶积算子的设计和反褶积处理，在实际资料处理中见到了明显的效果。此流程在保持信噪比不降低的情况下，使地震资料的分辨率和连续性均得到改善。
Deconvolution can enhance effective high-frequency contents but magnify high frequency noises to lower signal/noise ratio. Sometimes the effective high frequency contents enhanced by deconvolution can be submerged in noises, thus failing to improve seismic resolution. Both design of deconvolution operator and deconvolution processing can be achieved by revising the effective power spectrum of seismic waves. Good effect has been seen in real data processing. The method improves both the resolution and continuity of seismic data, without damaging the signal/noise ratio.
