针对层状、速度横向变化的黄土结构静校正问题,建立地形起伏较大的层状地震模型并正演模拟,对此分别进行折射和层析静校正的处理及对比,进而得到叠加剖面对比图,并结合实际资料的验证,得出:在层状速度结构的黄土塬地区静校正问题上,层析静校正能解决长短波长静校正问题,而折射静校正只能部分解决长短波长静校正问题,存在一定的高低频误差。
Aiming at the problem of static correction of the loess structure with lateral velocity and lateral velocity variation, a layered seismic model with a large topography fluctuation is established and forward modeling is performed. Then, the refraction and chromatographic static correction are compared and processed respectively, , And verified with the actual data, it is concluded that the tomographic static correction can solve the long-short wavelength static correction problem in the layered velocity structure of the static correction of the Loess Plateau, while the refraction static correction can only partly solve the long-short wavelength static correction , There is a certain high and low frequency error.
