Qingshankou-Formation Gravity-Flow Sedimentation in Early Cretaceous Songliao Basin of Northeast China: Evidences from Seismic Attributions Identification and Drilling Cores

Abstract:

In order to fine the description and prediction the sedimentary microfacies of Qingshankou-Formation high-frequency sequence stratigraphic framework and search for new sandbody reservoir 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 isochronal strata frameworks are established, and then the seismic sedimentology is studied, 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, storm and other types of sedimentary gravity flow, study finds deposition and depositional slope break and earthquake triggering mechanism, mountain torrents and other related.
