Abstract：The seismic tomography velocity analysis algorithm recommended here includes the following steps: 1.Make preliminary LIMO correction of reciprocal seismic reflection events in reversed multiple coverage records by making use of referen-cc velocity, then perform linear scan stack on short segements with the use of unequal time-differences, resulting in directional summedrecord in time domain;2.Automatically compare the summed seismic records so a.s to pick up usable waves but remove regular noises;3.Accurately determine reflection time-difference parameter and the reflector dip, but remove the effective velocity influenced by dip,thus gaining the real velocity distribution of seismic section.
