D6—2型补偿声速测井仪,是在原JB—78型补偿声速测井仪的基础上改进而成的。它采用双发双收的工作程式。其特点是:显著地减小了测量误差;对声速测井中的主要干扰——碰撞干扰有强的抑制能力;在进行声速测井的同时,可完成所测井段声波时差的累计和记录,从而为声速测井资料用于地震勘探提供有利条件。此外,本机尚有面板轻小(约8公斤)、操作简便、耗电省(约40瓦)、成本低等优点。
D6-2 compensation sound velocity logging tool, is based on the original JB-78 compensation sound velocity logging tool based on improved. It uses double hair double income working program. Its features are: to significantly reduce the measurement error; for sound velocity logging in the main interference - a strong suppression of collision noise; sound velocity logging at the same time, the completion of the logging section of the acoustic time lag accumulated and recorded , Thus providing favorable conditions for sound velocity logging data for seismic exploration. In addition, the machine has a small panel (about 8 kg), easy to operate, power consumption (about 40 watts), low cost.
