通过研究古构造格局的演化，结合烃源岩热演化史、油气运聚史进行分析，首次在塔西南坳陷内划分了出寒武 系含油气系统。通过对已知油气藏成藏过程和圈闭形成期的分析，确定了出含油气系统关键事件和关键时期，认为海西 运动期以聚油为主，喜马拉雅运动期以聚气为主；寒武系含油气系统与其它含油气系统在垂向和平面上有复杂的组合 关系；最有利的油气勘探区带为群库恰克扭褶带和玛扎塔格扭褶带；主要勘探目标为海米塔格构造带的海米面背斜，其 次为巴楚隆起西端的家武系盐下圈闭——结东断鼻。 By studying the evolution of palaeo-tectonic structure and combining with the thermal evolution history of hydrocarbon source rocks and the hydrocarbon migration and accumulation history, the Cambrian oil-bearing system was first divided into the southwestern Tarim Basin. Based on the analysis of the process of hydrocarbon accumulation and the formation of traps, the key events and key periods of oil and gas system were identified. It is believed that the oil accumulation is dominant in the Hercynian period and that in the Himalayan period, There are complex vertical and horizontal assemblages between the Wu system petroleum system and other petroleum systems. The most favorable hydrocarbon exploration zones are the Qunkuchak kink and the Mazatag kink; the major exploration targets are Hermite anticline in the Hermitage tectonic belt, followed by the salt rift in the Jiawu uplift at the western end of the Bachu uplift.
