In the seismic data processing, velocity analysis is one of critical steps. Conventional velocity analysis method was difficult to effectively pick up when the velocity sembalance does not converge. So, we proposed an effective method of velocity analysis, which picked up the velocity on the percentage velocity scanning stack. The method has guided by stack. Different from the traditional method of velocity analysis, this method considered lateral direction and vertical direction, both directions. The method used geologic horizons. It can effectively overcome the difficult velocity extraction because the velocity semblance does not converge. The method is effective in the low SNR data.
