摘要

根据超声波在媒质中的波函数和边界条件,求出了油井中采油超声换能器的辐射阻抗,并讨论了超声波的频率、井液、水泥层、岩层对超声换能器辐射阻抗的影响。当超声波的频率、井液声速变化时,超声换能器辐射阻抗变化比较明显。

Abstract

According to the wave functions and the boundary

conditions , the radiation impedance of the ultrasonic

transducer using in oil extraction was deduced . The effect of

the ultrasonic frequency and the density and the sound speed

of the well liquid and cement stratum and the rock stratum

on the radiation impedance of the ultrasonic transducer were

discussed. It was obtained that the radiation impedance of

the ultrasonic transducer changes in evidence with the

ultrasonic frequency and the sound speed of the well liquid .
