对测井曲线的各种去噪方法进行总结，根据小波阈值去噪法的优越性，提出一种改进的自适应小波阈值去噪法。选取Matlab工具箱里自带的曲线和测井曲线进行小波阈值去噪测试，改进的自适应小波阈值方法去噪方面表现优秀。新方法在滤除噪声的同时还能更好地保留信号的细节。
對測井麯線的各種去譟方法進行總結，根據小波閾值去譟法的優越性，提齣一種改進的自適應小波閾值去譟法。選取Matlab工具箱裏自帶的麯線和測井麯線進行小波閾值去譟測試，改進的自適應小波閾值方法去譟方麵錶現優秀。新方法在濾除譟聲的同時還能更好地保留信號的細節。

The purpose is mainly to denoise the logging curve.After summarizing various denoising methods, we propose an im-proved adaptive wavelet threshold denoising method according to the advantages of wavelet threshold denoising method, and select 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.
