Abstract:

In this paper, the convolution model of synthetic seismic trace is replaced by the first Fredholm integrated equation, which is then solved by using Walsh equation. A variety of models have been tested on the computer and satisfactory results are obtained. Application of the method proposed in this paper is thus believed to be potentially prosperous.

Key words: Walsh function, Acoustic impedance, Inversion
