摘要:

2010 年3 月, 国家海洋局第一海洋研究所在渤海海域开展了深部地震探测试验, 试验过程中使用了3种海底地震仪(OBS), 包括德国的SEDIS Ⅵ型OBS、法国的MicrOBS 和中国的I-7C 型OBS 共计51 台。文章详细描述并比较了以上3 种OBS 的性能指标, 通过对比发现: I-7C 型OBS 的耦合技术比其他两种OBS 更加完善, 功耗和数据存储容量方面优势明显; I-7C 型OBS 和MicrOBS 在设置参数和充电时, 操作方便, 提升了海上工作效率; MicrOBS 的水听器性能略有优势, 获取的数据清晰度高, 连续性好; SEDIS VI 型OBS的垂直分量数据在三者之间最优。本文提出了OBS 的发展趋势: (1)小型化、便携式; (2)低功耗、大容量; (3)长周期、宽频带; (4)低成本, 易回收。最后简要介绍了本次海上试验过程、数据处理方法以及探测试验取得的成果。本次试验成功取得了渤海海域深部地球物理数据, 对开展该区域内的深部地质研究具有重要的意义。

Performance comparison of ocean bottom seismometers and their application in the Bohai Sea

Abstract:

In March 2010, the First Institute of Oceanography, State Oceanic Administration (SOA) has launched a deep seismic detection test in the Bohai Sea, using three types of 51 ocean bottom seismometers (OBSs) including SEDIS VI OBS, MicrOBS and I-7C OBS made in Germany, France and China, respectively. It was found through comparison that: OBS made in China is better than the other two OBSs in coupling technology, power consumption and data storage capacity; I-7C OBS and MicrOBS are very easy to operate and express high efficiency in the sea when setting parameters and charging; The hydrophone of MicrOBS is advancing and able to obtain data of high definition and continuity; SEDIS VI OBS has the best data collected from vertical component seismograph among the three types of OBSs. Our paper has pointed out the development trend of OBS: miniaturization, being portable, low-power consumption, high capacity, long period, broad band, low cost, and easily retrieving. The performance indexes of the three types of OBSs mentioned above were described in details and compared. The process of deep seismic detection test, data processing methods and the results achieved are described briefly.
