Abstract:In recent years,the people has gradually had comprehensive knowledge of superiority of imple-menting wide azimuth survey but flinched from more expensive acquisition cost because of higher folds and smaller bin size for wide azimuth survey.For that reason,through wide azimuth seismic data practically acquired in Junggar basin of the west China and taking the lighologic reservoirs as the explored targets,the paper conducted the correlation and analysis of wide/narrow azimuth surveying effects.In studyings,we adopted processing techniques improving resolution in which the amplitude is strictly relative preserved and appreciated the ability of wide/narrow azimuth in exploring lithologic reservoirs on the basis of the difference of seismic attributes along the reservoirs.The studied results showed that in view of lithologic seismic exploration,the wide azimuth (aspect is greater than 0.5) has better spatial imaging resolution than narrow azimuth while is unnecessary to keep high folds that are 60?80 folds being enough to meet exploration demand on lithologic exploration in conditions of the areas having flat beds (hinterland of basin) and seismic data having certain S/N ratio.
