Ordovician Petroleum Accumulation System in Tazhong Low Uplift of Tarim Basin
-
摘要: 国外含油气系统的概念和方法在国内的含油气盆地研究中的应用存在着局限, 应用油气成藏体系的理论方法对塔中低凸起奥陶系油气成藏过程进行了分析.塔中低凸起奥陶纪油气成藏体系的源岩为寒武系及下奥陶统烃源岩; 满加尔坳陷中的砂体和不整合面是油气侧向运移的输导体, 同时深部断裂是油气垂向运移的输导体; 圈闭类型主要为古隆起背景上的地层型圈闭和构造型圈闭.塔中Ⅰ号断裂构造带是最为有利的油气聚集区, 塔中北坡次之, 中央断垒带最差.塔中Ⅰ号断裂带依然是下一步勘探的重中之重.Abstract: The concepts and methods of petroleum system are applied to analyze the Ordovician petroleum accumulation process in Tazhong low uplift of central Tarim basin. Hydrocarbon in the Ordovician petroleum accumulation system originated from the Cambrian and Lower Ordovician source rocks. Sand beds and unconformities in the Manjiaer depression are taken as the pathway of lateral petroleum migration and deep faults as the pathway of vertical petroleum migration. Main traps are composed of stratigraphic and structural typed traps developed in palaeo structural high. The results indicate that the area in the No.1 fault in Tazhong structure is inferred to be the most favorable zone of petroleum accumulation, and next, the northern slope of Tazhong structure, and the worst one, the middle fault-horst zone. Of them, the No.1 fault zone in Tazhong structure would be taken as the favorable prospect of next exploration.
