  • deconvolution : 反旋卷
  1. The clues and techniques to improve the resolution of data processing are 1 ) removing the affection of near surface factors on data acquisition, including static correction and noise eliminating technique etc, 2 ) broadening the frequency band of pre - stack seismic data, including amplitude compensation and pre - stack deconvolution etc, 3 ) improving s / n ratio of high frequency and weak reflection signals through multiple coverage with high precision velocity analysis, residual static correction and high - order nmo, raising " dead line of high frequency reflection ", and 4 ) identifying post stack effective reflection frequency band, enhancing dominant frequency and so on

    主要包括：消除近地表因素對資料採集的影響，包括靜校正和噪音壓制技術等；疊前拓寬地震資料領帶，包括振幅補償和疊前反褶積技術等；藉助高精度速度分析、剩餘靜校正和高次項nmo技術，通過多次覆蓋疊加，消除資料中隨機噪聲干擾、提高資料信噪比，尤其是高頻端反射信息的信噪比，改善高頻反射和弱反射信號信噪比，提高「高頻反射死亡線」 ；疊後有限反射頗帶識別、抬高優勢頻率等。
  2. We discussed common methods of digital deconvolution and analyzed effects of noise on it. then, we simulated digital deconvolution filters and optimization criteria of filtration parameters. after that, we gave the application of them in the frequency band extension technique
