在详细分析塔里木盆地西南坳陷地面地质资料和大量高质量地震剖面的基础上，依据圈闭的成因和特征，将塔西南坳陷的圈闭分为构造圈闭和非构造圈闭两大类，前者又细分为背斜圈闭和断层圈闭两亚类。圈闭的形成与发育受构造运动控制，圈闭的分布与断裂构造带展布有明显的依存关系。构造圈闭是塔西南坳陷油气富集的主要场所，油气聚集空间分布规律依赖于圈闭的空间展布规律。圈闭叠加有利于复式油气聚集带的形成，圈闭保存直接影响油气保存。不同期圈闭有不同的控制油气聚集作用。
Based on the detailed analysis of the ground geological data and a large number of high-quality seismic sections in the southwest depression of the Tarim Basin, the traps in the southwestern Tarim Basin are divided into two major categories: structural traps and non-structural traps, based on the genesis and characteristics of traps. , The former is subdivided into two sub-categories of anticline traps and fault traps. The formation and development of traps are controlled by the tectonic movement, and the distribution of traps is obviously dependent on the distribution of fault structure zones. The tectonic traps are the main sites for petroleum enrichment in the southwestern Tarim Basin. The spatial distribution of oil and gas accumulation depends on the spatial distribution of traps. Trapping superposition is conducive to the formation of multiple oil and gas accumulation zone, trap preservation has a direct impact on oil and gas conservation. Different periods have different control of hydrocarbon accumulation.
