Abstract

Abstract: The purpose is mainly to denoise the logging curve. After summarizing various denoising methods, we propose an improved adaptive wavelet threshold denoising method according to the advantages of wavelet threshold denoising method, and select 〖JP2〗Matlab toolboxs curve and well logging curve to test wavelet threshold denoising. The improved adaptive wavelet threshold denosing method is of good performance. The novel method can not only filter out noise, but also reserve the details of the signal better.〖JP〗
