【摘要】 目前常用的高分辨率地震资料缺少低频、频带窄、振幅谱不平,不利于构造和储层的精细解释。本文介绍的保幅宽频高分辨率处理以相对振幅保持为重点、以提高信噪比为基础、以展宽频带为目标,将高保真、高信噪比、高分辨率有机结合,获得的地震资料分辨率高、信噪比高,有利于识别小断层、薄互层和不整合面。

【Abstract】 The problems which exist in high resolution processing, such as shortage of low frequency, narrow frequency band and andunsmooth spectrum, are not beneficial to the fine interpretation of structure and reservoir at present. The high resolution processing of amplitude retention and broad frequency, taking the preserved amplitude as emphasis, improving the signal to noise ratio as bases, widening the band as target, combines high fidelity, high signal to noise ratio and high resolution to get high resolution and high signal to noise ratio, so it is beneficial to identify small fault, thin interbed and surface of unconformity.
