摘要：

This paper was based on the acoustic propagation mechanism in the oil pipe, the transmission model is established, dispersion equation and spectral distribution equation are derived, and the attenuation characteristics of acoustic propagation is analyzed. The simulation experiments show when the acoustic propagation process in the periodic oil pipe, the spectrogram appears to be the periodic comb filter structure, meanwhile the overall frequency distribution presents center symmetrical rule. The results show that the calculating method can simulate the acoustic propagation in the periodic oil pipe efficiently. It provides a theoretical basis and criterion on how to identify and analyze the carrier frequency of acoustic data propagation technology in the oil pipe.
