    基于潮位预测的潮汐校正方法在高分辨率单道地震调查中的应用

    Application of tidal correction method based on tide prediction in high resolution single-channel seismic survey

    • 摘要: 单道地震探测技术在海洋勘探各领域应用广泛,潮汐变化对高分辨率单道地震资料的质量有很大影响,尤其是对采集时间跨度较大的资料,在测线交点处存在严重的剖面不闭合现象。利用潮汐预测方法对高分辨率单道地震进行了潮汐校正,经过校正后的资料品质明显得到提升。通过对比不同测线交点处的剖面情况,剖面不闭合现象得到改善,同相轴的对应关系更好。实际应用结果表明,基于潮位预测的潮汐校正方法在高分辨率单道地震调查中的应用有效可靠。

       

      Abstract: Single channel seismic detection technology is widely used in various fields of marine exploration. Tidal variation has a significant effect on the quality of high-resolution single-channel seismic data. Data with a large acquisition time span often have non-closure of profile at the intersection of survey line. A tide prediction method was used to correct high-resolution single-channel seismic data and the data quality were improved obviously. By comparing profiles at intersection of different survey lines, the non-closure problem was eliminated, and the corresponding events become more continuous. Real case application showed that the tidal correction method based on tide prediction was effective and reliable in high-resolution single-channel seismic survey.
