Abstract：Routine seismic data processings are only for the seismic data whose signal/ noise ratio is high enough.Seismic data in ZL sandbar area have low S/N ratio,so routine data processing methods don't work well.But many experiments resulted in high S/N seismic sections which can be well used in seismic data interpretation.In data processing,we took measures in three fields:(1)estimation of field statics data, (2)shallow refraction noise removal using linear dynamic correction and f-k filter- ing,and(3)improving the S/N ratio of seismic section with the use of amplitude compensation,beam steering,coherency and high accuracy stacking.
