ON PALAEOGENE SEISMIC STRATIGRAPHY IN LANGGU DEPRESSION

Firstly, five major types and distribution patterns for seismic and sedimentary facies o Palaeogene in Langgu depression were analysed with the basis of geology, logging, seismic informations. Next, the authors described the characteristics of each facies type of seismics and sedimentation,and suggested the lateral distribution of the seismic facies and sedimentary facies is of asymmetric and vertical evolution with a succession and difference. Finally, areas favourable for petroleum exploration are predicted.
