| Abstract: | The paper introduces the logging curves filtering principle based on wavelet thresholding method ,anlyses the thresholds and wavelet thresholding functions characteristics, then an improved wavelet threshold denoising method is proposed. The simulation experiment of Heavisine signal and logging curves example results show that, the improved wavelet thresholding method can preserve curves datails well while reducing noise efficiently and it can get good application in logging curves denoise processing. |
