Abstract:In the desert area of South Xinjiang,the stratum is gentle with the continuous event and the depths from shallow to deep are relatively complete. However,there is often a phenomenon that the information of the events between the original single shots at different positions is quite different in many aspects including the number,definition,and relative energy relationship. It is shown that the same event exists in one shot but does not exist in another shot. Or,it is very clear in some single shots,but appears very weak in other single shots,seeming that these events “jump up and down” between single shots. In this case,the construction technicians are struggling to select the typical single shot of comparable quality and display it in the work area. It is inferred that the sand dune ringing in each arrangement is various,leading to the prominent difference in the quality of single shot data. The quality of single shot recording tends to be unified after suppressing the sand dune ringing. At the same time,the characteristics of sand dune ringing wave field are clarified through theoretical calculation and comparative analysis of actual data. On this basis,the corresponding suppression methods are further improved.
