| 摘 要： | 通过对塔里木盆地晚第三纪-第四纪沉积环境、沉积中心分布特征、构造变形特征及其动力学成因的分析，认为塔里木盆地晚第三纪-第四纪的沉积和构造变形过程明显受控于阿合奇-西昆仑-阿尔金左行剪切挤压构造。它加速了生油岩的成熟过程，形成新的背斜和断层圈闭构造，而且还控制了新生代油气的运移和聚集。非构造圈闭和断层遮挡圈闭所形成的次生油气藏是巴楚断隆的有利勘探目标。

| Abstract: | The analyses of Neogene Quaternary sedimentary environment, depocenter distribution and geodynamic origin of structural deformation of the Tarim Basin suggest that Aheqi West Kunlun Altyn sinistral transpression tectonics controlled the Neogene Quaternary sedimentation and structural deformation of the Tarim basin. It accelerated the hydrocarbon maturation process, formed many new anticline and fault traps, and controlled Cenozoic hydrocarbon migration and accumulation. The secondary oil and gas accumulation in the non structural traps and fault screened traps are favorable prospecting targets on the Bachu uplift. |
