Abstract：Higher resolution seismic data are needed in today's reservoir identifications.But higher resolution of seismic data is at all time limited by practical trouble,theoretical puzzle and customary behavior.Residual wavelets have to be handed down after the deconvolution.The band-limited wavelet has become the deadline of to improve resolution.The conventional pattern of explanation turns into the golden rule.So we first have to free from the puzzle,then to shake off the custom,and to overcome the trouble on purpose of to improve resolution of seismic data.
