摘　　要：针对塔城盆地勘探程度低、构造及演化认识不清等关键问题,运用构造解析理论,搞清了研究区"两坳夹一隆"的构造格局;利用平衡剖面技术恢复了构造演化历程并明确了对烃源岩发育与热演化的控制作用。研究区发育泥盆系和石炭系2套主力烃源岩层系、砂砾岩与火山岩2种类型储层、纵向深大断裂与横向不整合面复合输导体系,建立了古生古储型和古生新储型2类油气成藏模式,指出了下步有利勘探方向。Tacheng Basin is mainly challenged by low exploration degree and uncertainty of structural evolution,the'one uplift in-between two depressions'structural framework. Balanced cross section technology is used to recover the structural evolution process and the control to hydrocarbon source rock development and thermal evolution. Two major hydrocarbon source formations of Devonian and Carboniferous,two reservoir types of glutenite and volcanic and composite migration system of longitudinal deep faults and unconformity planes are developed in the studied zone. Two hydrocarbon accumulation modes of paleo- generation and paleo- accumulation,paleo- generation and new- accumulation are established,which indicate further favorable exploration.
