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
