摘要

随着地震勘探的发展,勘探区域日趋复杂化。地表起伏大,横向岩性速度变化剧烈,低降速带横向厚度分布不均匀等因素带来的静校正问题更加突出,解决好静校正问题变得尤其重要。在讨论层析静校正原理以及分析延川南地区地震资料的基础上,采用层析静校正方法较好地解决了长波长静校正问题,有利于延川南地区地震资料后期的处理解释。
With the development of seismic survey,conditions in exploration area are becoming more complex.Because the problem of static correction caused by undulating surface,fierce lateral lithologic velocity variation and uneven transverse gage distribution in low velocity belt becomes prominent,it is important to resolve it in seismic data processing.Based on the discussion of tomographic statics correction principle and analysis of seismic data in south YanChuan area,the long wavelength correction problem has been solved by means of tomographic statics correction,contributing to later processing and interpretation for its seismic data.
