Application Research on Improving Signal-to-noise Ratio Technology in the Exposed Limestone Area of Southeastern Sichuan
The southeastern region of Sichuan is affected by the exposure of near surface limestone,resulting in weak seismic data energy,developed interference waves,and low signal-to-noise ratio of the data.This article explores the application of low signal-to-noise ratio seismic data in the mountainous limestone exposed area of southeastern Sichuan to improve signal-to-noise ratio technology.By analyzing the characteristics and distribution range of different interference waves on the original data,and combining the advantages and disadvantages of various existing denoising methods,a combined denoising method that effectively improves the signal-to-noise ratio of the data is proposed,and its effectiveness in practical applications is evaluated.The actual application results of the data show that this combined denoising method can significantly improve the signal-to-noise ratio of geological data in the limestone area of the southeastern Sichuan mountain area while maintaining fidelity and amplitude,thereby providing more accurate and reliable data for subsequent imaging processing.
