In view of the low signal to noise ratio seismic data character of Yanqi basin, the author made large quantities of analyses and tests and, on such a basis,designed a low signal to noise ratio seismic data processing framework dominated by such processing methods as interactive iterative static correction technique, the technique for suppressing stochastic interference and linear interference, suface compatibility amplitude proccessing technique, wavelet normalization proccessing and denoise technique of post interactive f-x domain prediction. Practical data proccessing has proved the framework to be evidently effective.
