摘　　要：地震数据显示是地震采集质量监控的重要工具,可以及时发现野外采集单炮数据的异常。介绍了地震采集现场常用的单道均衡、多道均衡、固定增益、自动增益控制(AGC)4种显示方式和均方根、平均值、最大值3种均衡因子计算方法,以及每种显示方式在地震采集现场的应用技巧,为地震采集单炮数据现场分析与质控提供思路。Seismic data display is an important tool for monitoring the quality of seismic acquisition,which can timely detect abnormal single shot data in the field.This article introduces four display methods commonly used in seismic acquisition,such as single trace balance,multi-trace balance,fixed gain,automatic gain control(AGC)and three calculation methods of balance factor,including root mean square,mean and maximum,as well as the application skills of each display method in seismic acquisition sites,which provides an idea for field analysis and quality control of single shot seismic acquisition data.

关 键 词：地震数据 单道均衡 多道均衡 固定增益 自动增益控制(AGC)
