| 摘 要： | 论述了塔里木盆地的地球动力学演化过程，指出震旦-三叠纪和侏罗-第四纪是两个构造巨旋回．在这类旋回中，盆地经历了由伸展到聚敛的完整发育过程塔里木盆地的演化总体上表现为强伸展-聚敛-微伸展-强聚敛的特点盆地动力学旋回决定了油气的生运聚散过程．提出含油气系统旋口的概念．在分析寒武-奥陶系含油气系统旋回、石炭系-下二叠统含油气系统旋回和侏罗系含油气系统旋回的基础上，指出对含油气系统旋回的形成期与调整再分配期的研究更具实际意义．

| Abstract: | This paper discussed the gdriyndric processes of Tarim basin. The basin had undergone two tectonic mega-cycles, Sinian to Triassic and Jurassic to Quaternary, and subjected to a full process from extension to convergence in such a mega-cycle. The geodynamic evolution Of the basin has been characterized by the process from strong extension to moderate contraction and once again from weak extension to strong convergence. Such geodynamic cycles had played a great role in the hydrocarbon generation, migration, accUmulation and dispersion, The paper sUggested the concept of Petroleum system cycle, and analyzed the Petroleum system cycles of Cambrian to Ordovician, Carboniferous to lower Permian and Jurassic etc. The paper also proposed the studies of the Pened of formation and redistribution of the Petroleum system cycle more practical. |
