PSZJ-1型声波全波列测井仪在固井质量检测中应用

PSZJ-1声波全波列测井仪是煤炭系统首台小口径固井质量检查测井仪器,可用于测量自然伽马、套管接箍、声波时差、声幅、声波全波列五种参数。在固井质量检查测井时,根据声幅测井曲线的高（〉90%）和低（〈10%）以及声波变密度测井图上有无波形或波形的规则程度,可有效检查水泥环胶结质量,评价第一界面和第二界面的胶结情况。二个实例表明该仪器在固井质量检测中具有较好的应用效果。

Application of PSZJ-1 Acoustic Full-wave Train Logger in Well Cementing Detection

The PSZJ-1 full-wave train acoustic logger is the first logging instrument used in slim hole well cementing quality detection in coal industry,can measure five parameters of gamma-ray,casing coupling,sonic differential time,acoustic amplitude and acoustic full-wave train.During well cementing quality detection logging,based on acoustic amplitude traces high(>90%) and low(<10%),have or have not waveforms on acoustic variable density log or waveform regularity can evaluate cementing quality of cement ring,cementing situation of first and second interfaces.Two examples have demonstrated that the instrument has good application effects.
