塔里木盆地西南拗陷是长期发展演化的复合前陆拗陷。它在新生代经历了早第三纪构造宁静期、中新世构造主要发展期、上新世构造宁静期和第四纪构造定型期．构造变形以印度板块与欧亚大陆板块的碰撞及幕式推挤为背景，以发育冲断－褶皱和快速沉降为特征．自后陆向前陆，构造变形由强到弱．不同构造单元构造的变形也有其特点。盆地沉降是构造负载与沉积负载共同作用的结果。喜山构造运动不仅加速了烃源岩热演化，而且还产生了大量与断层相关的褶皱，为油气运聚提供了良好的条件．
The southwestern depression in the Tarim Basin is a long-term evolutionary composite foreland depression. It experienced Cenozoic tectonic transect in the Cenozoic and the main development period of Miocene tectonic. The Pliocene constructed Quaternary tectonic setting period. Tectonic deformation is based on the collision between India plate and Eurasia plate and the curtain-type thrusting, characterized by the development of thrust-fold and rapid subsidence. From the land to the foreland, structural deformation from strong to weak. The deformation of different tectonic units also has its own characteristics. Basin subsidence is the result of a combination of tectonic load and sedimentary load. The Himalayan tectonic movement not only accelerated the thermal evolution of source rocks, but also produced a large number of fault-related folds, which provided good conditions for hydrocarbon migration and accumulation.
