通过研究塔里木盆地轮南及其周缘地区残余构造特征、断裂展布、剖面性质和该地区晚海西期构造定型的运动学过程和成因机制、构造定型后的油气成藏机制，认为该地区晚海西期的构造变形是在早古生代变形基础上的叠加，是加里东期与海西期构造应力联合作用的结果，而且每期应力都控制着与该应力近于垂直的逆断层和与其平行的走滑断层的发育；深埋的下古生界的长期生油和持续供油，为轮南地区多期成藏及成藏油气的叠加、复合改造提供了物质条件，是该地区油气性质多样的根本原因；古斜坡长期发育是油气成藏的重要条件；多层位有效储盖组合与多期成藏是油气成藏的主要机制。

Through research on characteristics of remaining structure, fault distribution and its profile’s property in Lunnan and its peripheral area in north Tarim basin, this article analyzes the kinematical process and origin mechanism of the structural finalization of this area in later Hercynian period, and discusses the pool\|forming mechanism of oil and gas after the structural finalization. The deformation of this area in the later Hercynian period is a stack on the basis of deformation in early Eopaleozoic, and it is also the result of integrated action of tectonic stresses in the Cambrian and Hercynian periods. Every period’s stress controls the development of faults vertical to the stress and strike-slip faults parallel to it. The long\|period oil generation and continuous oil supply by the deeply buried lower Paleozoic provides material conditions for the multistage pooling, the stack of pooling oil and gas and the multi reconstruction. This also leads to rich and colorful oil and gas in the area. Palaeo-slope of long period is an important condition of pool foramation, and the efficient association between reservoirs and traps of multi strata and the multistage pooling are the most important mechanism.
