This paper studied the present development status of migration imaging on interpretation of quasi three dimensional seismic data of gas hydrate, and concluded the problems of poststack migration and analyzed the characteristics of main prestack migration algorithms. It is believed that Kirchhoff integral method is little affected by the irregularity of geometry and intense changes of velocity and is favorable to prestack migration processing of quasi three dimensional seismic data of gas hydrate. Kirchhoff integral method prestack migration was applied to process the quasi three dimensional seismic data collected in Shenhu area in northern
