声测井是以研究井下岩石声学特性为基础的多种测井方法。这是利用介质对声波传播速度和声能吸收的差异,借以探测岩石的性质解决井下地质问题。声测井的主要方法有声速测井、声幅测井、声波全波列测井,以及超声成像测井等。本文主要阐述了煤田地质勘探的声测井的物理基础、声速测井、声幅测井等技术问题。
Acoustic logging is a variety of logging methods based on the study of the acoustic properties of downhole rock. This is the use of media on the sound velocity and acoustic energy absorption differences, in order to detect the nature of the rock to solve underground geological problems. Acoustic logging is the main method of sound velocity logging, sound amplitude logging, acoustic wave train, and ultrasonic imaging logging. This paper mainly elaborates the physical basis of acoustic logging for geological prospecting in coalfields, sound velocity logging, sound amplitude logging and other technical problems.
