Abstract:

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.
