摘　　要：阿克库勒凸起的油气勘探开发取得了重要的地质成果，但受研究区多期构造运动叠加改造的影响和资料的限制，对该区的构造发展演化过程缺乏系统、统一的认识。在最新的3D、2D地震资料解释成果的基础上，通过平衡剖面恢复，结合古构造变形特征的复原．进一步厘清了阿克库勒凸起的构造演化过程。加里东中期－海西期为鼻凸形成、抬升、剥蚀期；印支－燕山期，继承性发展；喜山期构造调整定型。在此基础上，结合油气分布和勘探情况，发现阿克库勒凸起油气成藏受构造演化发展的控制明显．形成了4个油气成藏期。The oil and gas exploration and development in Akekule Uplift has made important geological progresses, but the development and evolution of the tectonic processes has been lacking of systematic and uniform understanding due to the superposition of multi-stage transformation and influence of tectonic movement and data constraint in the study area. On the basis of the latest 3D and 2D interpretation of seismic profiles, through the restoration of the balanced cross-section and combined with the characteristics of ancient tectonic deformation recovery, the process of tectonic evolution in Akekule Uplift is further clarified. In the interim Caledonian - Hercynian period, the nose convex shape was formed, uplifted and eroded. In lndosinian-Yanshanian epoch, it developed succeedingly. In Himalayan period, the structure was adjusted and shaped. On that basis and combined with the oil and gas distribution and exploration, we found that the hydrocarbon accumulation in Akekule Uplift was controlled by the tectonic evolution development obviously and four hydrocarbon accumulation periods were formed.
