| 摘 要： | 为了检验光纤水听器阵列在海洋地震勘探中应用的性能, 在南海, 使用1024基元的光纤水听器阵列与进口的360道压电水听器海洋地震勘探仪, 采用相同的作业方式在同一位置进行海洋地震勘探调查, 对两个设备采集的海洋地震勘探资料进行对比。试验结果表明, 光纤水听器阵列采集的数据主频范围达到10~120Hz, 宽于压电水听器海洋地震勘探仪的主频范围10~80Hz; 地震剖面分辨率优于压电水听器海洋地震勘探仪。光纤水听器阵列在经过适应性改进后完全能够满足海洋地震勘探的性能要求。

| Abstract: | In order to test the performance of fiber optic hydrophone array in marine seismic exploration, we carried out a test in the South China Sea. We used the same mode of operation in the same location for marine seismic exploration, using the 1024 channels fiber-optical hydrophone array and the 360 channels piezoelectric hydrophone imported marine seismic exploration devices. Then, we compared the marine seismic exploration data collected by the two setups. The test results show that the frequency range of the data collected by the fiber optic hydrophone array reached 10-120 Hz, which is wider than 10-80 Hz of the piezoelectric hydrophone marine seismic exploration devices. The resolution ratio of seismic section is better than that of piezoelectric hydrophone marine seismic exploration devices. After some adaptive improvements, the fiber optic hydrophone array can satisfy the performance requirements of marine seismic exploration. |
