摘要	Inverse problems arise naturally in oil geophysical exploration. In order to detect the structures of oil/gas objects, one of the most important step in seismic data processing is that we need to know the velocity information of subsurface. This belongs to scope of seismic inversion. There are various seismic inversion methods to achieve the goal, for example the seismic tomography based on ray tracing and the conventional velocity analysis based on CDP stack. Currently, the popular method is the full-waveform inversion (FWI) method based on wave equations. The FWI method uses the prestack data rather than the poststack data as an input and has high accuracy to image complicated velocity structures. The inversion can be implemented in the time domain or in the frequency domain. While there are many works of frequency-domain FWI methods, here we focus on the time-domain FWI method and try to inverse complicated velocity structures.
