摘    要:DMO(倾角时差校正)是一种将非零偏移距地震道转换为零偏移距地震道的数据处理方法,主要针对地层倾角不为零的情况。通过应用DMO,共中心点道集变成以自激自收(垂直入射)定义的共深度点道集。DMO是地震资料处理中一个非常重要的流程,对DMO的发展状况和一些主要算法进行总结,各向异性DMO将有望成为今后的发展方向。

关 键 词:倾角时差校正  叠前部分偏移  地震资料处理  地震勘探

Abstract:DMO (dip movout operater) is a technique for transforming non - zero - offset seismic data to true zero- offset location and reflection time , especially in the presence of dip. After DMO, each common midpoint (CMP) gather of traces actually contains events from the same depth point, as defined by the normal incidence ray. DMO is an important procedure in conventional processing , so here we summarize some key development in the history and the main algorithms of DMO process techniques. It can be anticipated that the DMO operators in the anisotropy media will be dominant in the near future.
Keywords:dip moveout  prestack partial migration  seismic data processing
