摘要

在陆上激发地层疏松或海上施工存在气泡的情况下,采集的资料经常存在一种短周期鸣震。鸣震干扰能量较强,对资料品质影响严重,通常采用的压制方法很难将其有效消除。本文结合WCH三维地震资料的处理及以往经验,总结出预测反褶积与区域相干噪声衰减组合的方法用于压制鸣震干扰,取得了较好的效果。
A short-period reverberation called "hollow-reverberation" exists in the seismic data when the operations are conducted on near-surface geological structure on land or offshore. This reverberation is bad for the quality of data because of its energy is powerful, and it is difficult to remove it by the conventional noise suppressing technique.Combined with the previous experience and the processing of the 3D seismic data acquired from Wacheng in Weibei area, a method which is a combination of predictive deconvolution and zone coherent noise attenuation was developed to attenuate the hollow reverberation, and has achieved a good result.
