海洋地震儀OBS簡(jiǎn)介及技術(shù)參數(shù)中英文

1、海洋地震儀 OBS 簡(jiǎn)介Ocean Bottom Seismometer主要用途海底地震儀OBS(Ocean Bottom Seismometer)是一種放置于海底的地震數(shù)據(jù)采集系統(tǒng)， 可用于記錄天然地震事件和人工地震勘探， 廣泛應(yīng)用于油氣勘探、 地球深部結(jié)構(gòu)探測(cè)等領(lǐng)域。 由于儀器位于海底，可以同時(shí)接收P波和S波信號(hào)，且環(huán)境噪音低，實(shí)現(xiàn)高信噪比、高分辨 率和高精度的海底地震數(shù)據(jù)采集。Application：OBS(Ocean Bottom Seismometer)is a seismic data acquisition system which placed in the seabed,ab

2、le to record the natural earthquake and human seismic exploration, it is widely used for Oil & gasexploration, deep exploration of earth structure and other fields. Since the device is in the seabed, itcould receive the signal of P wave and S wave at the same time, with a low noise environment,

3、thedata acquisition is realized the high signal to noise ratio, high resolution and high accuracy.主要特點(diǎn)1.可采集4分量的地震信號(hào)，分辨率高，一致性好；2.采用寬頻帶地震計(jì)，可適應(yīng)海底較大的傾斜角，自動(dòng)調(diào)整水平；3.低功耗運(yùn)行，連續(xù)長(zhǎng)期海下工作；4.萬(wàn)米級(jí)工作水深；5.高精度GPS授時(shí)，水面自定位；6.人機(jī)友好交互，方便查看儀器狀態(tài)；Main Features:1.Get 4 channels seismic signal, high resolution and Good consistenc
