圆管状声波换能器瞬态过程的分析

结合石油测井的实际情况,首次从理论上对常规声波测井仪中采用的圆管状压电陶瓷声波换能器在阶跃电压、冲激电压和正弦间断电压等激励信号的作用下的瞬态过程进行了分析,推导出了在上述几种情况下圆管状压电陶瓷换能器的声源函数和谱函数,并叙述了推导结果在声皮测井中的应用。

Analysis of Transient Process of Cylindrical Acoustic Transducer.

For the first time, this paper, theoretically, analyses the transient processes of the cylindrical piezocrystal acoustic transducer which is excited by the step voltage, the impulse voltage and the discontinuous sine voltage, and then derives the transducer's functions of sonic source and spectrum from the above cases. The application of the above functions to the sonic logging is also discussed.
