Sonic logging has been seldom applied in average velocity field, owing to some limits of data collection and defection of sonic logging.
在平均速度场研究中很少利用声波测井资料，这是因为声波测井资料本身的缺陷所致。
Logging sonic differential time and seismic interval velocity are used to estimate formation pressure in this paper.
讨论了利用测井声波时差和地震层速度预测地层压力的方法及其应用。
