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 consistency2. 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1. 宽频带长周期四通道海底地震仪：甚宽频带( 120s-50Hz )；标准宽频带( 60s-50Hz ；30s-100Hz )；部分120s 和60s OBS 为双球体或四球体等，以满足检波器固置空间和海底能源供应的需仪器尺寸：舱球600X 600 X 700 mm；投放尺寸：含沉耦架900 X 900X 1000 mm；耐压水深：6000 m、9000 m、12000m三种规格；通道数：四通道(3分量速度检波器，1通道水听器) 连续工作时长：10 ~ 15个月；最大回收周期：24个月；检波器频带：60 s ~ 50 Hz ，电容换能地震计；可选120 s、60 s和30 s ~ 50Hz 任意带宽；地震计功耗：0.15 w ；水听器频带：0.1 Hz ~ 20k Hz ；动态范围：>120 dB ；整机功耗：0.25 w ；采样率：250，100，50 sps ；内置高精度时钟：OCXO, 0.01 PPM@C;自储存容量：32 GB;仪器状态设置：Wifi接口；地震数据传输：USB2.0标准；仪器重量：65 kg (不含沉耦架)；沉耦架重量：25 kg ；1、Broad Band Frequency Long Period Four ChannelOBSBroad Ba nd Freque ncy (120s-50Hz)；Standard Frequency (60s-50Hz ；30s-100Hz)；part of 120s and 60s OBS is double ball or four ball structure to meet the dema nd of the in built geopho ne space and sea power.OBS Size: 600 X00 >700 mm ；Sink size with dead weight : 900 X900 X000 mm ；Operating depth(Max) : 6000 m、9000 m、12000m three types ；Chann els：Four (3 aixs geopho ne , 1 cha nnel hydroph one)；Worki ng time : 10 ~ 15 mon ths ；Max recycling time : 24 month ；Geophone frequency: 60 s ~ 50 Hz, Capacitive energy seismometer ；120 s、60 s & 30 s ~ 50Hz is optional ；Geophone power consumption : 0.15 w ；Hydroph one freque ncy : 0.1 Hz ~ 20k Hz ；Dynamic range : >120 dB ；Overall Power Consumption : 0.25 w ；Sample rate：250, 100, 50 sps;in built Built in high precisi on clock : ocxo, 0.01 PPM@4C；Storage：32 GB ;OBS stateme nt sett ing: Wifi in terface ;Data transmission : USB2.0 StandardOBS Base weight: 65 kg (not include dead weight );Dead weight: 25 kg ;2、短周期四通道海底地震仪仪器尺寸：舱球600X 600 X 700 mm；投放尺寸：含沉耦架900 X 900X 1000 mm;耐压水深：6000 m、9000m；通道数：四通道(3分量速度检波器，1通道水听器)；连续工作时长：10个月；最大回收周期：15个月；检波器频带：0.1 Hz ~ 100 Hz ;可选0.1 Hz、0.2 Hz、0.5 Hz、1 Hz、2 Hz ~ 100 Hz检波器功耗：0.04 w ;水听器频带：0.1 Hz ~ 20k Hz ;动态范围：> 120 dB ;整机功耗：0.15 w ;采样率：500, 250, 100 sps ;内置高精度时钟：OCXO, 0.01 PPM@C ;自储存容量：32 GB ;仪器状态设置：Wifi接口;地震数据传输：USB2.0标准;仪器重量：44 kg (不含沉耦架)；沉耦架重量：20 ~ 25 kg ;2.Short Period Four Cha nnel OBSOBS Size: 600 X00 >700 mm ;Sink size with dead weight : 900 X900 X000 mm ;Operating depth(Max) : 6000 m、9000 mChann els：Four (3 aixs geopho ne , 1 cha nnel hydroph one); Work ing time : 10 mon ths; Max recycli ng time : 15 mon ths ;Geophone frequency: 0.1 Hz ~ 100 Hz ;0.1 Hz、0.2 Hz、0.5 Hz、1 Hz、2 Hz ~ 100 Hz are optional; Geophone power consumption : 0.04 w ;Hydroph one freque ncy : 0.1 Hz ~ 20k Hz ;Dynamic range : >120 dB ;Overall Power Consumption : 0.15 w;Sample rate：500, 250, 100 sps;In built Built in high precisi on clock : OCXO, 0.01 PPM@4 °C；Storage：32 GB ; OBS stateme nt sett ing: Wifi in terface ;Data transmission : USB2.0 StandardOBS Base weight: 44kg （not include dead weight）;Dead weight: 20 ~ 25 kg3、便携式海底地震仪仪器尺寸：舱球400X 400 X 600 mm；投放尺寸：含沉耦架700 X 700X 800 mm耐压水深：6000 m ;通道数：四通道（3分量速度检波器，1通道水听器）；连续工作时长：2个月；最大回收周期：6个月；检波器频带：1 Hz ~ 200 Hz ；可选1 Hz、2 Hz、4.5Hz~ 200 Hz 任意带宽；检波器功耗：0.04 w ；水听器频带：0.1 Hz ~ 20k Hz ；动态范围：> 120 dB ；整机功耗：0.15 w ；采样率：500, 250, 100 sps ；内置高精度时钟：OCXO, 0.01 PPM@C;自储存容量：32 GB;仪器状态设置：Wifi接口；地震数据传输：USB2.0标准；仪器重量：22 kg （不含沉耦架）；沉耦架重量：10 ~ 15 kg3.Portable OBSOBS Size: 400 x 400 x 600 mm;Sink size with dead weight : 700 x 700 x 800 mm ;Operating depth(Max) : 6000 mChannels: Four(3 aixs geophone ，1 channel hydrophone)；Working time : 2 months；Max recycling time : 6 months ；Geophone frequency: 1 Hz ~ 200 Hz；0 1 Hz、2 Hz 、4.5Hz~ 200 Hz are optional ；Geophone power consumption : 0.04 w；Hydrophone frequency : 0.1 Hz ~ 20k Hz ；Dynamic range: >120 dB；Overall Power Consumption : 0.15 w；Sample rate: 500，250，100 sps;In built Built in high precisi on clock : OCXO, 0.01 PPM@4 °C；Storage：32 GB ；OBS statement setting：Wifi interface ；Data transmission：USB2.0 StandardOBS Base weight ：22kg(not include dead weight )；Dead weight ：10 ~ 15 kg。
