【摘要】 近年来,静校正技术在复杂地区地震数据处理中起着举足轻重的作用。回折波走时层析反演是一个全三维反演方法,它是用回折波或连续折射直达波通过高精度的交互反演近地表介质速度变化,进而计算静校正量的过程,它适用任意观测系统的二维或三维地震资料。将此方法应用在某地资料处理中,提高处理剖面质量,尤其在解决长波长静校正方面,取得了明显效果,与其它同类静校正技术相比有独到之处。更多还原

【Abstract】 recently the static correction plays an important role in seismic data processing.The bow tie travel-time Tomographic Inversion,which records the near-surface velocity distribution by high accuracy interactive inversion of bow tie or continuous refraction direct arrival and can be used to calculate static correction value,is a kind of full-3D inversion that is adapt to 2D or 3D seismic data that acquired by discretional observation system.the quality of data processed in QingHai and Suligemiao area of Chang Qing oil field has improved greatly,particularly in the long wavelength static correction.Compared with other static correction methods,the Tomographic Inversion is an original method.更多还原
