近年来,在珠江口盆地东部的地震资料采集工作中,使用了一种较先进的仪器,即LRS-16型海上多道遥测系统。采集的地震测线达4300km左右。虽然为数不大,但从效果来看,在几乎相同的处理流程条件下,记录质量有明显改善:其一,分辨率高,波形特征清晰,能够较好地识别出详细的波组及层位;其二,干扰背景干净,断点清晰,地质异常体较突出;其三,整个记录的信噪比较高。在应用这一先进采集系统的同时,还选用了数
In recent years, an advanced instrument has been used in the seismic data acquisition in the east of the Pearl River Mouth Basin, namely the LRS-16 multi-channel maritime telemetry system. Seismic survey collected about 4300km. Although the numbers are small, the recording quality is significantly improved with almost the same processing flow under the same processing conditions. First, the resolution is high and the waveform features are clear, and the detailed wave set and horizon can be well identified Second, the interference background is clean, the breakpoints are clear, and the geological anomalies are more prominent. Thirdly, the signal-to-noise ratio of the entire record is relatively high. In the application of this advanced acquisition system at the same time, also selected a few
