摘要

It is possible to describe the seismic features of volcanic strata in geology using seismic parameter, seismic reflection configuration and phases, and seismic stratigraphy. Yingcheng Formation is a set of volcanic strata in which the volcanic rock is dominant in Xujiaweizi faulted depression of Songliao Basin. Matching both the drilling data and seismic data of Yingcheng formation can give some geological interpretations of seismic attribute, reflection configuration and phases. The seismic-geological interpretation of volcanic strata in the 3D seismic region of Xujiaaweizi faulted depression contains three aspects: seismic parameter, seismic reflection configuration and phases, and architecture of seismic strata, responding to the stratigraphic records of volcanism and related sedimentation. The seismic reflection configuration and phases are the key to the seismic-geological interpretation.
