针对碳酸盐岩地层的薄水泥环套管井情形，计算了声波合成波形，着重讨论了一界面和二界面流体环隙宽度变化的声波波形特征。合成波形及其频谱分析表明：套管波幅度、地层波幅度和波列后续波的持续时间均与流体环隙宽度有关。因此，利用套管波幅度和界面波持续时间等特性可估计流体微环宽度，利用界面波幅度和频率特性及其波列持续时间可作为固井质量评价的特征量。
For the case of thin cement cased hole in carbonate formation, the waveform of acoustic wave was calculated, and the characteristics of the acoustic waveform of the variation of annular gap width at interface 1 and interface 2 were emphatically discussed. Synthetic waveforms and their spectral analysis show that the amplitude of the casing wave, the amplitude of the formation wave and the duration of the wave following wave are all related to the width of the fluid annulus. Therefore, the width of the fluences of the fluid can be estimated by using the characteristics of the amplitude of the casing wave and the duration of the interface wave. The amplitude and frequency characteristics of the interface wave and the duration of the wave train can be used as the characteristic quantities of the cementing quality evaluation.
