古生物学的

Under the guidance of the theories of sedimentation, paleontology, stratigraphy, reservoir geology and digenesis, synthetically applying the methods of the conjunction of spot-line-surface, macro-microscopic and field-indoor, there is a comprehensive study for the upper Permian series in stratum, rock, sedimentary facies and diagenesis, especial for the type and characteristics of sedimentary facies, in the paper.
