Abstract
A seismic sedimentologic study is made in the theQingshankou-Formation in the northern Songliao Basin, based on 3D seismic operation area, the principles of seismic sedimentology and sequence stratigraphy in North Songliao Basin Qingshankou-Formation is ochronal strata frameworks are established, and then Seismic data is processed with t echnologies of phasing and stratal slicing and then the amplitude on slice is interpreted to obtain the planar distribution of reservoir. The sedimentary packing and evolving histories are restored in Qingshankou-Formation various types of gravity flow reservoirs are on the basis of gravity flow sedimentary structure identification of sliding rock, sandy debris flow, turbidite rock.
