摘　　要：以大陆动力学、构造地质学和含油气系统理论做指导,以盆地构造—沉积分析技术为手段,研究了塔东地区与南天山、阿尔金山之间的耦合关系,探讨了塔东地区的大地构造演化特征及其对油气成藏的控制,完善了塔东地区的油气成藏模式。指出:从中新生代以来,塔东地区与南天山、阿尔金山盆山耦合关系十分密切;构造是塔东地区沉积演化史的主控因素,控制了油气的生储盖成藏组合;侏罗系煤系露头的发现,为混源油气成藏模式提供了有利的证据。Based on theories of continent dynamics, tectonic geology and petroleum system, and guided by basin structure analysis and basin sedimentary analysis, the auther studied on the coupling of TianShan and Aljingshan in the east of Tarim basin, the purpose of it is to investigate on the geotectonic evolution and its controlling on the oil-gas formation, and improved its oil-gas formation model. The results in the paper show, ever since Mesozonic, the basin-mountain exists close relationship. The tectonic is the main controlling factor not only for the sedimentary evaluation history, but also for the combination of hydrocarbon generation rock, reservoir, and its cap-rocks. The discovery of Jurassic coal measure emergence, provided reliable evidence for a new oil-gas formation model in the paper oil-gas accumulation mixed source and secondary model in the east of Tarim basin. The discovery of Jurassic coal measure emergence is very significant not only for the study of oil-gas geological conditions but also for its oil-gas source evaluation in the east of the Tarim basin.
