Abstract：Regarding the residual static correction for large statics,the development of residual static correction technique which based on model trace was introduced in this paper.The related analysis was conducted and the reason for 'loop jump' which was caused by large residual statics to residual static correction inversion method which is based on model trace was found out.It is believed that if the product of the highest frequency of seismic wave and the largest residual statics is small,the model trace which is formed by stacking the traces in the CDP gather is reliable.In this paper the development of multiscale residual static correction technique which is based on model trace is introduced.Synthetic and real seismic data test show that the technique is effective and can solve 'loop jump' problem for large residual statics,the technique is not only as effective as non-linear inversion residual static correction techniques,but also as efficient as the linear inversion techniques.
