中、长波长静校正量严重影响了复杂地区地震资料的信噪比和在时间剖面上构造的准确性 ,也是长期困扰柴达木盆地复杂地区地震资料处理的技术难题之一。本文在总结前人研究成果的基础上 ,以扩展广义互换法(EGRM)折射静校正、交互迭代折射静校正方法为例 ,阐述了这两种方法的基本原理以及在柴达木盆地复杂地区地震资料处理中的应用 ,并对其应用效果进行了分析
Medium and long-wavelength static correction seriously affect the signal-to-noise ratio of seismic data in complex areas and the accuracy of the structure in the time profile. It is also one of the technical problems that long plagued the seismic data processing in complicated areas of the Qaidam basin. On the basis of summarizing the research achievements of predecessors, this paper expounds the basic principles of these two methods and the method of extending the static correction of EGRM and the iterative refraction static correction method, The application of seismic data processing, and the application effect is analyzed
