| 1. | 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 . based on the above , the vertical evolutionary model of the sedimentary environment is explained by the study of the elevation profile and transverse profile and the regional geological characteristics
本文主要是以沉积学、古生物学、地层学、储层地质学等相关理论为指导，运用点线面、野外与室内、宏观与微观相结合的方法，并借助普通显微镜、阴极发光显微镜等手段对川西地区北部上二叠统的地层、岩石、沉积相以及成岩作用进行了研究，尤其是对沉积相的类型及特征作了详细的划分与阐述。 |
