在地球物理常用的沃尔什函数法基础上，提出了声波测井曲线的沃尔什反演法；对反演过程的具体技术问题作了细致、深入的探索，总结出了逐点反演法和逐段反演法；并对临盘油田Ｌ２－３井的声波测井曲线进行了反演，取得了满意的效果。
Based on the Walsh function method commonly used in geophysics, the Walsh inversion method of acoustic logging curves is proposed. The detailed technical problems of the inversion process are explored in detail and the point-by-point inversion is concluded Method and section-by-section inversion method. The acoustic logging curves of L2-3 well in Linpan Oilfield are inverted and the satisfactory results are obtained.
