Embodiment 1
[0072] a. The simulated data model is a three-dimensional inclined formation model ( Figure 9a ). The observation system is set to 11 2000-meter-long survey lines with a distance of 100 meters and a near-parallel spread (-500m—500m). Seismic waves are excited at intervals of 25 meters at the horizontal position of the central cable, and the data are complemented by the reciprocity theorem to obtain the same seismic exploration data as the shot detection on the central survey line. Extract the gather according to the shot number (fldr, 1-81) in the track head information, and obtain the common shot point gather d(x k ,y k ,t,x s ,y s ); According to the detection number (tracl, (1-81, 1-11)), the gathers are extracted to obtain the common receiver point gather r(x r ,y r ,t,x k ,y k ), where (x k ,y k ) is any point position (shot point or receiver point), (x s ,y s ) is the shot point coordinates, (x r ,y r ) is the coordinates of the detection point, and t is t...
