摘要

目的更好地解决黄土塬地区非纵地震测线存在的严重静校正问题,提高地震资料品质。方法基于非纵勘探资料的特点,通过对多种静校正方法的对比试验分析,确定利用3D无射线追踪层析技术计算黄土塬地震静校正的方法。结果该方法消除了用常规方法处理黄土塬非纵地震资料时存在的长波长静校正问题,避免了其他方法引起的低幅度构造假象。结论该方法在黄土塬地区取得良好的静校正效果,获得了高质量的非纵地震叠加剖面,并在实际井位部署中发挥了有效的作用。
Aim To cope with the serious static correction problem more effectively,and to improve the quality of seismic data in Loess Plateau area.Methods Based on the characteristics of the off-line seismic data,it is decided to use 3D non ray-tracing tomographic static correction in Loess Plateau area after the analysis of the application of more static methods.Results By this technique,the long-wavelength static correction problem is eliminated in processing off-line seismic data in Loess Plateau area,which avoids low structures caused by other methods.Conclusion High quality stack sections are obtained by this method of static correction in loess Plateau area,which has guided well drilling successfully.
