| 摘 要： | 塔里木盆地内地表面巨厚的沙层是油气勘探的主要障碍。本文在构造解释中用切除法把地表面低速的、不稳定的沙层切除，然后通过折射波反演方法，得其厚度，从而提高了构造图的精度。

| Abstract: | In this article,a new maping method is intruduced,i.e. after removing the travel time corresponding to this unstable low velocity sand layer in seismic interpretation,them to get its thickness by refraction inversion.The precision in tectonic maps is greatly enhanced by this method. |
