海洋地震仪OBS简介

Ocean Bottom Seismometer

主要用途

海底地震仪OBS(Ocean Bottom Seismometer)是一种放置于海底的地震数据采集系统,可用于记录天然地震事件和人工地震勘探,广泛应用于油气勘探、地球深部结构探测等领域。由于仪器位于海底,可以同时接收P波和S波信号,且环境噪音低,实现高信噪比、高分辨率和高精度的海底地震数据采集。 Application:

OBS(Ocean Bottom Seismometer)is a seismic data acquisition system which placed in the seabed, able to record the natural earthquake and human seismic exploration, it is widely used for Oil & gas exploration, deep exploration of earth structure and other fields. Since the device is in the seabed, it could receive the signal of P wave and S wave at the same time, with a low noise environment, the data acquisition is realized the high signal to noise ratio, high resolution and high accuracy. 主要特点

1. 可采集4分量的地震信号,分辨率高,一致性好;

2. 采用宽频带地震计,可适应海底较大的倾斜角,自动调整水平; 3. 低功耗运行,连续长期海下工作; 4. 万米级工作水深;

5. 高精度GPS授时,水面自定位; 6. 人机友好交互,方便查看仪器状态; Main Features:

1. Get 4 channels seismic signal, high resolution and Good consistency 2. Adopt broad band seismic sensor, can adapt to the larger angle of the sea,

automatically adjust the level;

3. Low-power operation, continuously work underwater in long-terms; 4. work depth could reach 10000m;

5. High precision GPS timing, self-positioning;

6. Man-machine friendly interaction, easy to view the instrument state; 技术参数
