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：消除近地表因素对资料采集的影响，包括静校正和噪音压制技术等；叠前拓宽地震资料领带，包括振幅补偿和叠前反褶积技术等；借助高精度速度分析、剩余静校正和高次项nmo技术，通过多次覆盖叠加，消除资料中随机噪声干扰、提高资料信噪比，尤其是高频端反射信息的信噪比，改善高频反射和弱反射信号信噪比，提高“高频反射死亡线” ；叠后有限反射颇带识别、抬高优势频率等。
