%X Chuanxi area is located in the Sichuan basin, with abundant gas, complex structures. The bed of interest, carbonate reservoir, is deep in this area, with strong heterogeneity. Images of poststack time migration are poor in the Chuanxi area; however, results show that the high accuracy prestack time migration technique can effectively improve the image precision of seismic data. The result sections are characterized by clearer faults, reliable breakpoints. The results allowed for precise structural interpretation. This paper introduces the basic theory, main steps and application effects of the high accuracy prestack time migration.
