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采集的影響，包括靜校正和噪音壓制技術(shù)等；疊前拓寬地震資料領(lǐng)帶，包括振幅補(bǔ)償和疊前反褶積技術(shù)等；借助高精度速度分析、剩余靜校正和高次項(xiàng)nmo技術(shù)，通過多次覆蓋疊加，消除資料中隨機(jī)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” ；疊后有限反射頗帶識別、抬高優(yōu)勢頻率等。
