    • Abstract
  • In energy resource seismic prospecting,to best realize time difference correction of pre-stack tilted stratum,advance velocity analysis and overlay precision,present a sort of celerity realize pre-stack partial migration algorithm,called migration to zero offset(MZO) algorithm.The algorithm uses the technology of wave field extrapolation and the wave equation migration by finite difference approach,which can be used in common offset gathers,for 3D material requires common offset gathers with the same azimuth angle.By real data tests,considering adopting the clearly fast algorithm,the speed of calculation is two times faster than the allied NMO means,and even get the quite effects.
