摘要
为解决常规初至层析静校正方法因表层不均匀照明所导致的地下网格射线缺失的问题,GeoEast处理系统开发了菲涅尔层析静校正方法。GeoEast处理系统快速层析反演技术运算量小、反演速度快;菲涅尔层析反演技术反演速度精度高、稳定。在库车山地实际地震资料处理中初步取得了较好的效果。
Seismic data imaging is always affected by statics due to complicated near-surface structures in Kuqa, Tarim Basin. Conventional first-break tomo-statics do not work well on seismic data in mountain areas due to lack of rays. In recent years,some new statics approaches are developed such as fast tomography and Fresnel tomography under GeoEast. These approaches are characterized by fast calculation and high accuracy in inversion and achieve better statics results than conventional methods in the Kuqa Area.
