Abstract：Damingtun sag is a secondary structural unit in north part of Liaohe fault depression,where the surface condition and geologic structure are complex and reversed faults developed on east and west sides of depression that made seismic data processing work face with two urgently solved geologic issues: the one was the detail appreciation and lateral prediction of Paleogene Es3 and Es4 clastic reservoir; the other was accurate definition of local structure in steep slope zone and study of genetic mechanism.Taking 480 km2 of 3-D data finely acquired in recent years as background and data in deep formation of main structural parts and in east and west complex steep structural zone as objects, the paper developed and applied prestack depth migration of wave equation on shot domain and formed a set of imaging techniques and flow considering the feature of data in Damingtun sag.It was shown by practical data processing that imaging effects were significantly improved, 7 prospective traps were discovered and prospective oil-bearing area of 32.7km2
