摘要
塔西南动陷位于塔里木盆地西南部，发展演化受不同时期板块构造背景的控制，具明显的多期性，形成了3类原型盆地和3个含油气系统。这些原型盆地相互叠加改造，导致了现个凸凹相间的构造格局和含油气系统的叠加改造。依据盆地构造演化特征和烃源岩、储集岩、盖层发育特征，划分出3个含油气系统，分析了每类含油气系统的基本特征及可靠程度。
The development and evolution of the southwest depression in Tarim basin were controlled by the plate tectonic setting at different stages, forming three types of primary basin and various types of petroleum system, whose intersuperposition and reform led to the present sag and swell alternated structural pattern, and to the superposition and re form of petroleum systemsBased on the characteristics of tectonic evolution and that of the source, reservoir and cap rocks of the depression, three typesof petroleum systems have been identified, and the primary characteristics and the reliability of each type of petroleum sys-tems are analyzed.
