起伏地表直接叠前时间偏移
Keywords: 叠前时间偏移,起伏地表,地震数据处理,共成像孔径面,剩余时差校正
Abstract:
？针对起伏地表直接进行叠前时间偏移是目前复杂山地地震资料叠前成像处理的方向。如今研究的侧重点是通过参考面计算起伏地表条件下的地震波走时,进而进行叠前时间偏移,但是这—过程存在两个问题:其—是参考面选择不当会因高差和替换速度的不准确而带来走时计算误差;其二是地震数据经常规处理返回到采集地表面时可能破坏高频静校正效果。基于此,本文提出了以共成像孔径面为参考面且在共反射点道集上进行剩余时差校正的起伏地表叠前时间偏移的方法。文中分别应用简单模型、seg起伏地表模型以及实际资料对该处理方法进行了测试,表明该方法是有效的。
