使用Promax进行坏道编辑

Using Promax for edit of abnormal traces

在地震数据处理中,手工进行坏道编辑是一项繁重而又枯燥的工作,尤其是三维地震资料,处理员有时需要数十天的时间才能完成这项工怍。本文提供了一种将人工判定与Promax相关心理模块相结合的综合方法进行坏道编辑。该法包括以下几步:不同类型震源的分离,带通滤波,频率统计,频率域极值拾取,相关模块去除坏道。该方法能提高坏道编辑的工作效率,尤其是适用于三维项目。

In seismic data processing, the manual edit of abnormal traces is strenuous and dull work, especially for 3-D seismic data that makes processor spend dozens days to finish this job. The paper provided integrative approach combining manual i-dentification with processing module Promax to carry out the edit of abnormal traces. The approach included following steps: separation of different type of sources,band-pass filtering,frequency statistics, extreme pickup in frequency domain and elimination of abnormal traces by using relevant module. The approach can improve the efficiency of edit of abnormal traces,which is especially suitable for 3-D project.
