海上地震系统低频响应与电缆噪音

The Low-frequency Response of Marine Seismic System and the Steamer Noise

海上勘探地震采集的数据中低频率成分常常受到外部环境噪音的严重干扰。如何有效地剔除噪音 ,拾取更多的地震数据中低频成分。本文从分析地震仪器低频响应入手 ,得出了地震系统与电缆噪音的一些内在联系 ,就如何有效地压制外围环境噪音等问题 ,提供了有效的方法 。

The low frequency component in acquired data from the marine seismic curvey is seriously interfered by the ambient noise frequently How to reduce the affection from the ambient noise to get more effective low frequency component from seismic data In this paper, the authors analyze the low frequency response of seismic system, get some relationship between the low frequency seismic system and the ambient noise, and present a better method to reduce the ambient noise It' s a good reference for the marine seismic fidle operation
