| 摘 要： | 采用沃尔什函数法对声波测井（时差）曲线进行反演，得出地层的真实时差，可使声波测井曲线的垂向分辨率由０．６ｍ提高到０．２５ｍ，增强了曲线的薄层识别能力。从理论上分析了的反演结果的分辨率和方差特点，对模型数据和实际资料进行处理表明该方法是可行的。

| Abstract: | The true acoustic slowness of the examined beds is found out from the normal acoustics slowness by means of Walsh functions. The vertical resolution of the normal acoustic slowness is enhanced from 0. 6 m to 0. 25 m. Recognization ability of the acoustic slowness for the thin or ultra thin bed is strengthened. In addition. the resolution and the variance of the slowness inversion is theoretically analysed. The processing results of the model and the field data demonstrate that the method is efficient. |
