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。
