摘要
塔里木盆地塔北隆起已在10个层系(组)获得工业油气流,发现4大类13种类型油气藏。结合烃源条件、圈闭条件、储盖组合及保存条件,分析了油气藏的形成及演化。指出塔北隆起带油气藏的主要特点是:类型多、含油气层系(组)多、成藏期多、埋藏深、规模不大、沿断裂及不整合面分布。隆起带内的油气富集受区域构造格局控制,并可分为南部的海相油气系统和北部的陆相油气系统。
Commercial oil/gas flows have been obtained in ten layer series in Tabei uplift of Tarim basin, and four categories, thirteen types of reservoirs have been found. Based on source rock, trap, reservoir cap assemblage and preservation conditions, formation and evolution of reservoirs were analysed. It is considered that the reservoirs in Tabei uplift are characterized by multiple types, multiple layer series, mutiple reservoir formed stages, deep burial, small scales and distribution along faults and unconformable surface. Hydrocarbon accumulation in Tabei uplift belt was controlled by regional structure framework, and divided into a marine petroliferous system in south and a continental petroliferous system in north.
