Deep raw seismic records in southern Songliao Basin have many problems such as low ratio of signal to noise,all kinds of noise,low receiving energy and severe static correction caused by complex surface. In order to overcome these difficulties,multi-system including CGG,Focus,Grisys Promax was used to select advanced modules. Key techniques have been studied and tested including involved refraction static correction,deconvolution,remain static correction,migration,DipMoveOut,which provides an effective method to handle the seismic information in this area.
