复杂条件下三维地震资料处理中的几个关键问题

Key issues of 3-D seismic data processing under complicated geologic settings

在详细介绍了本区地震地质条件和资料采集情况的基础上 ,分析了在本区进行精细资料处理中的难点 ,指出并讨论了 4个方面的关键问题 :一次静校正和剩余静校正问题、叠前去噪问题、反褶积问题和速度问题。最后 ,对比分析了本区三维地震资料新。

Based on the detailed knowledge of seismic geological conditions and survey layout in Gangkou Yuxi area, this paper discusses the difficulties encountered during the fine processing for 3 D seismic data from the area, and points out that 4 key issues should be paid great attention to. They are primary statics and residual static correction, pre stack denoising, deconvolution, and velocity. A comparison between results from this work and the existing 3 D seismic data is also given in the paper.
