摘　　要：陈爱新，钟兴水，聂在平．测井资料沃尔什反演．测井技术，１９９８，２２（２）：９１～９３简述了沃尔什反演的基本原理，讨论了该方法的误差情况。为了验证该方法的有效性，利用沃尔什反演方法处理了一口井的测井资料，并对反演结果进行了测井解释。解释结果表明，经沃尔什反演得到的高分辨率测井曲线的纵向分辨率明显高于原始测井曲线，地层界面变得非常清晰，而且解释结果接近于取心数据，说明反演结果与地层实际情况相符合。The basic principle of Walsh inversion and its error are described. In order to prove the validity of the given method, it is used to process logs from one well and the inversed results are analysed. The interpretation results show that the vertical resolution of the logs inversed by Walsh function is much higher than that of raw data with clear formation boundary,and they are very close to core data, indicating the inversion values agree with the true formation values.
