复杂地表区地震资料静校正方法探讨

Discussion on the Static Correction of Seismic Data in Complex Surface Area

静校正技术是地震成像的核心技术,基于复杂地表区的地震资料特点,通过不同的静校正方法试验对比,探索出一条综合利用层析静校正解决长波长静校正问题、折射波剩余静校正解决中短波长静校正问题、反射波剩余静校正解决短波长静校正问题的静校正思路,有效地解决了复杂地表区的静校正问题,使地震资料成像效果得到了显著提升。

The static correction technology is the core of the seismic imaging technology, based on the characteristics of seismic data of complex surface area, through experiment contrast different static correction methods, a way of comprehensive utilization of tomographic static correction long wavelength static correction problem, refraction residual static correction long medium short wave static correction problem, residual static correction of reflection wave static correction approach to solve the problem of short wavelength static correction was explored, which effectively solved the complex surface correction problem, and made the seismic data imaging effect significantly increased.
