How to effectively improve the signal-noise ratio(SNR)of seismic acquisition data at home and abroad is one of the topics that every field has been trying to overcome and is limited by climate,topography,construction parameters and various uncertain factors,The technical means to improve the signal to noise ratio can not be generalized.This article discusses the construction parameters and methods,relying on the Sinopec Saudi S55 2D and S62 3D seismic exploration project.Through the exploration and construction of the Seismic Geophysical Branch of Sinopec Geophysical Exploration Company over the years in the Rub Al-Khali Desert,Saudi Arabia,the paper investigated and analyzed various major factors affecting the seismic exploration acquisition quality in the area,and accumulated and explored a large number of letters of improvement Noise ratio method.At the same time,the method of improving signal-to-noise ratio(SNR),which is widely used in seismological acquisition of seismogenic vibrator nowadays,is combined and analyzed according to the standards of relevant collection technology of Saudi National Petroleum Company.Based on the practical application in the project,A series of pertinent experiments were carried out based on the related analysis methods of the Saudi Aramco seismic acquisition project to achieve high signal-to-noise(SNR)acquisition of exploration data tasks in the desert.Through the analysis and research on the conventional sources of interference in the area,the combination of source scanning movement excitation technology,large area sawtooth combination detection technology and multiple coverage technologies,the dissertation improves and innovated it in a targeted way,The construction method of improving signal to noise ratio in desert area provides good technical support for seismic exploration data acquisition.It is hoped that this construction method can provide reference for the future construction of the desert exploration market at home and abroad so as to enhance the status and reputation of Sinopec Exploration Market and contribute to the expansion of Sinopec's oil exploration and development market.
