回声测深仪是用来测量水深的一种声学测量设备，其以水中超声波的传播速度为确定条件，利用发射波与反射回波时间差来测量水深。
Echo Sounder is a kind of acoustic measuring depth equipment, which can measure depth with the time between transmitted wave and echo on condition in which the speed of ultrasonic is fixed.
人工地震波、电磁波和声波的频率越高，分辨率越高，但衰减快，可探测深度也降低。
The higher the frequency of the artificial earthquake wave, electromagnetic wave and sonic wave, the higher the resolution, but the attenuation is very fast and the exploration depth is very shallow.
根据这些曲线的变化，简单分析了声波测井的探测深度。
In this paper, radial investigation depth of acoustic logging is researched with the well that is surrounded by the cylindrical multi-layer media.
