摘要 针对现有声波测井资料利用效率和精度较低的情况,有必要对声波数据进行校正。提出了影响声波数据质量的因素,利用时差与到时、时差与其他测井曲线进行对比分析,用地质和数学的方法相结合,检查声波测井数据质量,得到声波曲线数据质量检查的结果。最后利用井径与声波时差的关系制作交会图,并设计了校正曲线对声波时差进行校正。 Aimed at the low utilization efficiency of acoustic logging data and precision, it is necessary to correct acoustic data. This pa-per put forward the influencing factors on the quality of the sound wave data, and used the time difference and then, time difference with other logging curves were analyzed. Combined with geological and mathematical methods, the quality of acoustic logging data was checked ,and the results of quality inspection for sound wave curve data can be gained. In the end,by using the relationship between the diameters of holes and the time difference of acoustic wave,the relevant cross plot was obtained,and the calibration curve was also de-signed to correct the time difference of acoustic wave.
