摘要
Abstract
With the acceleration of social development and urbanization,seismic data acquisition is facing increasingly severe envi-ronmental noise impacts.The effective control of environmental noise is the most effective measure to improve the signal-to-noise ra-tio of seismic data.However,with the introduction of high-density seismic exploration technology and the integration of technology and economy,the contradiction between efficient seismic acquisition and strict control of complex noise is becoming increasingly severe.Therefore,it is particularly important to find the balance point between the quality of seismic data and the efficiency of seismic acquisi-tion.This article first analyzes the characteristics of environmental noise in the Sichuan basin and its control measures;Secondly,the impact of environmental noise of different intensities on seismic data was analyzed,and the attenuation effect of environmental noise of different intensities was analyzed;Finally,the threshold value of environmental noise that needs to be controlled is found through the attenuation effect of different intensities of environmental noise.Research has shown that environmental noise with an intensity below 20μV has a relatively small impact on seismic data evaluation,while environmental noise with an intensity below 40μV can be effectively attenuated through seismic processing technology.关键词
