摘要
随着海洋地震数据处理技术的进步,在地震采集作业中,需要实时监控气枪震源近场子波的变化,将近场子波信号记录到地震数据的辅助道,用于后期的远场子波推算。本文分析了近场子波信号实时监控与记录存在的问题,如近场检波器在气枪阵列中的位置,近场子波信号输入辅助道的匹配,监控与存储的软件设置等,并提出了解决方案。
With the progress of marine seismic data processing technology, we need real-time monitor the variety of air gun source near-field wavelet in seismic acquisition operation, and record the signal to the seismic system auxiliary channel which is calculated for the far-field wavelet. This paper analyze the problems in near-field wavelet signal real-time monitoring and recording, such as the near field detector position in the air-gun array, match between near field wavelet signal and auxiliary channel, software settings for monitoring and storage, puts forward a kind of solution. Through the application of this scheme, the nearfield wavelet signal real time monitoring and data storage is achieved.
