Embodiment Construction
[0028] Hereinafter, exemplary embodiments according to the present invention will be described in detail with reference to the accompanying drawings.
[0029] figure 1 A flowchart illustrating a modeling method of a layer velocity model of a formation according to an embodiment of the present invention.
[0030] In step 101, a seismic wave excitation method is used to generate seismic waves in the work area, and seismic data are collected.
[0031] In step 102, conventional horizontal stack imaging processing and post-stack time migration imaging processing are performed on the seismic data, thereby obtaining horizontal stack imaging data and post-stack time migration imaging data.
[0032] Horizontal stacking imaging processing and post-stack time migration imaging processing are relatively mature technologies. The more common post-stack time migration imaging processing is to perform post-stack time migration on the horizontal stacked imaging data after proper correction o...
