摘要
Velocity analysis is an essential procedure in the processing flow for extracting rock velocity of P-wave and S-wave from full wave sonic logging data.This paper introduces the acoustic waveform component in the well field,suggests a similar correlation velocity analysis algorithm and studies the key factors which influence the results of velocity analysis,such as band-pass filter,window width,total time stack and low velocity layers.Through discussion and analysis,we gave the values of these procesing parameters in the velocity analysis.This may have very important guiding significance for extracting the rock velocity of P-wave and S-wave accurately.
