Abstract: This paper focuses on the dissemination problem of the low strain reflection in the wave impedance medium.  Throughout analyzing the influencing factors and echoing characters of the low strain reflection signals, etc., the analysis of more clear and distinctive signals can be achieved. The interpretation of the signal can be verified by the coring results.
