| 摘 要： | 中国含油气盆地以叠合盆地为主，经历多期次构造运动，造成盆地内部多期古隆起的复合叠加；目前对于多期活动古隆起复合叠加过程的解析研究较为薄弱。本文以塔里木盆地轮南古隆起为例，利用最新的三维地震数据和钻井资料，应用构造解析和古构造复原的方法，明确轮南古隆起经历寒武纪-早中奥陶世前古隆起、晚奥陶世古隆起形成、晚泥盆-早石炭世叠加改造、晚二叠世-三叠纪古隆起定型、侏罗纪-古近纪古隆起埋藏和新近纪以来构造掀斜6个演化阶段；揭示现今以寒武-奥陶系碳酸盐岩为主体的前中生界隆起是由位于研究区西北侧北东向展布的晚奥陶世古隆起、研究区中部北北东向展布的晚泥盆-早石炭世古隆起和研究区北侧近东西向展布的晚二叠世-三叠纪古隆起三者复合叠加而成；不同时期古隆起成因机制有差异，但都与盆地周缘洋盆闭合、造山作用关系密切。

| Abstract: | China''s petroliferous basins are mainly superimposed basins, which have experienced multiple periods of tectonic movement, resulting in the composite superposition of multiple periods of paleo-uplifts. At present, the research on the superimposition process of multiphase active paleo-uplifts is relatively weak. The article takes the Lunnan paleo-uplift of the Tarim Basin as an example to carry out paleo-structural restoration, using the new-acquired 3D seismic data and drilling data, applying structural analysis and paleo-structural restoration methods. The formation and evolution process of the Lunnan paleo-uplift is divided into six stages. From the Cambrian to Early-Middle Ordovician is pre-paleo-uplift period. The Late Ordovician is paleo-uplift formation period. From the Late Devonian to Early Carboniferous is superimposed reconstruction period. From the Late Permian to Triassic is stereotype period. The Jurassic-Paleogene is buried period. The paleo-uplift is titled since the Neogene. The present pre-Mesozoic uplift mainly composed of Cambrian-Ordovician carbonate rocks is a composite of the NE-trending Late Ordovician paleo-uplift located in the northwest part of the study area, the NNE-trending Late Devonian-Early Carboniferous paleo-uplift located in the middle of the study area and the nearly WE trending Late Permian to Triassic paleo-uplift located in the north part of the study area. The formation and evolution process of the study area is closely related to the opening and closing and orogenic movement of paleo-ocean basins around the basin. |
