【Abstract】 The method of regional seismic stratigraphy should be improved in someaspects due to the differences between fault-depressed continental basins andmarine basins. The meaning of reflectional terminals varied from kind tokind. Seismic sequences should be discriminated into supersequences, sequencesand subsequences according to the scale of unconformity. In the analysisof seismic facies, a reasonable program should be followed, and the internalcombination of seismic facies, the gully - fan connection and the velocity -petrology parameters should be considered in addition to geometrical andphysical parameters. The interpretation of seismic facies into correspondentdepositional facies must be combined with well data as much as posible, andthe seismic facies must be concordant with core facies ahd well-log facies.The study of the Langfang-Gu’an depression has provided an example ofabove approach.更多还原
