声波时差测井是最常用的岩性—孔隙度测井方法之一。本文阐述了声波时差的工作原理,结合现场实际工作经验分析了声波曲线影响因素,介绍了现场声速验收方法以及故障分析。
Acoustic time-of-flight logging is one of the most commonly used lithology-porosity logging methods. This article elaborates the working principle of the acoustic time difference, analyzes the influencing factors of the acoustic curve according to the actual working experience in the field, introduces the method of field acoustic velocity acceptance and the fault analysis.
