The Tube wave detection is a new downhole geophysical technique used in geological engineering in recent years.Based upon the observed data of tube waves,this paper tries to analyze the kinematic characteristics of the different phases in the Tube wave field.The results from this analysis show that the technique not only can detects t the integrity of a downhole,but also can map the variation of the geological structure along the downhole by the traveltimes of refracted Tube wave from the drill wall.Meanwhile,the unknown phases R * is found in this study,the phase R * should be the twice reflection of phase R1 acoording to the twice traveltimes of the original reflections.
