摘要： 塔里木盆地从震旦纪至今经历了多期次的构造运动, 包括挤压逆冲运动和伸展运动, 但以前者为主。这两种运动在盆地演化中至少有两次更替, 前中生代的挤压逆冲运动在中生代变为伸展运动, 至新生代又被挤压逆冲运动所代替。这两种运动的交替变化就产生了负反转构造和正反转构造。塔里木盆地的反转构造与油气的生成、运移、聚集、保存有着密切的关系, 为大中型油气田的形成提供了良好的构造条件。

Abstract: Tarim basin has undergone many times of tectonic movements since Sinian period, including compressional thrust movement which is dominated and extensional movement. These movements had at least two alternatives during evolution of the basin, that is, compressional thrust movement in pre-Mesozoic became extensional movement in Mesozoic: but the later was in turn replaced by compressional thrust movement in Cenozoic. These alternative changes, however, could form negative and positive reversed structures. Reversed structure in Tarim basin has close relations with its oil generation, migration, accumulation and preservation, providing a good structural environment for the form of giant and middle oil and gas fields in it.
