摘要
Based on nonlinear tomographic inversion, phase belt plot of velocity model in plane section, and short refraction and minilog data as initial model, the authors make the tomographic inversion improve the vertical inversion precision and special reasonability. For the high frequency static correction values that have imaging advantage, the authors piece together, then use function interpolation at boundary. Thus, the imaging advantage of different methods in a 3D block can be used. The 3D static correction technology has been used in some complex areas, and the results have been gotten.
