摘要: 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。

Abstract: Based on Walsh function commonly used in geophysics, an inversion algorithm of the acoustic logging curve is presented.The actual technique of inversion process is discussed deliberately and two inversion methods, point by point method and interval by interval method, are concluded. As an example, the acoustic logging curve of the L2-3 well in Linpan Reservoir was inversed and the result is satisfactory.

Key words: Walsh Function, Acoustical Logging, Inversion
