塔里木盆地反转构造与油气聚集

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运动，至新生代又被挤逆冲运动所代替。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。

Hu Wangshui .REVERSED STRUCTUCTURE AND HYDROCARBON ACCUMULATION IN TARIM BASIN.

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 aIternatives during evolution of the basin,that is,compressional thrust movement in pre-Mesozoic became extensional movement inMesozoic;but the later was in turn replaced by compressional thrust movement in Ceno-zoic. These alternative changes,however,could form negative and positive reversed struc-tures. Reversed structure in Tarim basin has close relations with its oil generation, migra-tion, accumulation and preservation, providing a good structural environment for the formof giant and iniddle oil and gas fields in it.
