声波时差是岩石机械物理性质的综合体现。声波测井资料可以用来进行钻速的预测。本文依据塔里木牙哈地区的实际资料，阐述了这一方法的应用，并提出了进一步的研究方向。
Acoustic wave time difference is a comprehensive manifestation of the physical properties of rock machinery. Sonic logging data can be used to predict drill-bit penetration. Based on the actual data of Yaha, Tarim, this paper expounds the application of this method and puts forward further research directions.
