阿克库勒凸起隶属满加尔含油系统的北部,其寒武-奥陶系烃源岩在加里东晚期-海西早期和印支-喜山期两次生油,据此并结合油气藏的形成和破坏将该区油气藏演化分为寒武-二叠纪和三叠纪以后两个阶段。这两个阶段具有相同的源岩和不同的成藏条件。阶段1和阶段2的关键时刻分别为海西中期和喜山期。

Akekule uplift is situated in the north part of Manjiar petroliferous system.Oil generation of its Cambrian-Ordovician source rocks started in late Caledonian-early Hercynian and IndoChina Himalayan periods.Combine this with the formation and destruction of oil and gas reservoirs in the study area,reservoir evolution could be divided into Cambrian-Permian and Post Triassic stages.Though the source rooks of the two evolution stages were the same,the formation conditions of the reservoirs were different.The key periods of the two stages were middle Hercynian and Himalayan epoches respectively.
