摘　　要：文章推导出声波测井圆管状压电陶瓷技能器传输函数，得出换能器有两个谐振中心频率：串联谐振中心频率和并联谐振中心频率。分析计算了谐振中心频率偏移对声波测井曲线的影响。Acoustic logging cylindrical piezoelectricceramic transducer transmission function is derived in the paper, with which two transducer frequencies, i. e. series resonance center frequency and parallel resonance center frequency are obtained. The effect of resonance center frequncy deviation on acoustic logs is analyzed here.
