摘　　要：常规噪音,无论是规则噪音还是随机噪音,都是采集中不可避免产生的。虽然噪音类型相同,但由于激发震源不同,也会给噪音特征带来影响。可控震源超高效混叠采集施工方式不可避免地带来了震源机械干扰,谐波干扰等噪音。本文针对AHV-326型可控震源在80 Hz左右出现的噪音干扰,通过野外大量实验数据,利用可控震源独立测试软件Sandwichbox对各部位采集的信号进行幅频特性分析和干扰能量分级,找出这一干扰的产生的位置和原因,并根据机械隔振原理消除了AHV-326型可控震源在80 Hz的噪音干扰。Conventional noise is inevitably generated in the acquisition process whether regular noise or random noise.Although the noise type is the same,it will also affect the noise characteristics due to different excitation sources.The construction method of ultra efficient blended seismic acquisition inevitably brings the noise of vibration source such as mechanical interference and harmonic interference.This article aims at the noise interference of AHV-326 vibrator around 80 Hz,through a large number of experimental data in the field,utilizing Sandwichbox,which is an independent vibroseis testing software,to analyze the amplitude,frequency characteristics of noise,the disturbance energy classification and find out the reason for this interference.According to the principle of mechanical isolating vibration,the noise interference of AHV-326 vibrator at 80 Hz is eliminated.
