巴楚凸起是塔里木盆地油气富集单元之一,自奥陶纪以来经历了多次隆升剥蚀与下降沉积的交替过程,经喜马拉雅运动期的断裂褶皱、抬升剥蚀,定型为塔西南前陆盆地的前缘隆起。巴楚凸起发育下寒武统、中-上奥陶统以及石炭系3套烃源岩,奥陶系碳酸盐岩、石炭系碳酸盐岩和碎屑岩3套储集层,5套区域性盖层。圈闭形成于晚海西运动期和喜马拉雅运动期,主要类型为与断层有关的断垒和断鼻。在巴楚凸起有2种基本的油气聚集模式,即石炭系断背斜型和下奥陶统断块山及披覆背斜复合型油气聚集,油气沿断层及不整合面注入储集层,分布受古隆起、断裂、不整合及裂缝等因素的控制。
Bachu Bulge is one of the oil and gas enrichment units in the Tarim Basin. Since the Ordovician period, it has undergone several alternations of uplifting and descending sedimentation. After the Himalayan movement, The front edge of the basin is uplifted. There are three sets of reservoir rocks in the Lower Cambrian, Middle-Upper Ordovician and Carboniferous, three sets of Ordovician carbonate rocks, Carboniferous carbonate rocks and clastic rocks. Set of regional cap layer. Traps formed in the Late Hercynian and Himalayan motions, and the main types were fault-related break barriers and broken nose. There are two basic modes of hydrocarbon accumulation in Bachu, that is, hydrocarbon accumulation of Carboniferous ancillary syncline, Lower Ordovician fault block and drape anticline, and oil and gas injection along the faults and unconformities into reservoirs, Distribution by the paleo uplift, fracture, unconformity and cracks and other factors control.
