| 摘 要： | 多次波的压制是海洋地震资料处理中的重要步骤。海洋地震勘探中的多次波一般都异常发育且较难压制,压制多次波的好坏直接决定了处理结果的质量。目前压制多次波的方法有很多种,但不同的方法基于不同的理论,具有不同的针对性。单一的方法压制多次波往往不能针对所有多次波,达不到理想的效果。笔者使用组合衰减多次波技术,综合了SRME、拉东变换、LIFT去噪对海洋实际地震数据的多次波进行压制,取得了较好的效果。

| Abstract: | Antimultiple processing is an important step in marine seismic data processing.The multiple waves in marine seismic data are generally rather strong and very difficult to suppress,so the suppression of multiple waves decides the quality of processing results.There are many ways to suppress multiple waves;nevertheless,different approaches are based on different theories and have different targets.A single method can not suppress all multiple waves and hence fails to achieve the desired results.The authors em... |
