Abstract

Based on tectonic evolution and Jurassic petroleum geological conditions in NE Sichuan basin, we discussed the oil and gas geological characteristics and main tactors of hydrocarbon accumulation. NE Sichuan basin went through the transformational history from large fresh water depression basin after inland craton to foreland basin of Daba mountain. Based on hydrocarbon generation and migration in the foreland basin of north Sichuan, tectonic evolution and trap types in Daba mountain, we illustrated the main control factors of oil and gas accumulation in Daanzhai Member, Lianggaoshan Formation and Shaximiao Formation in Jurassic of the NE Sichuan. We pointed out that the formation of Jurassic oil reservoirs would be at the late diagenetic stage, since source rock started to generate a large number of hydrocarbons and accumulation after diagenesis compression, suggesting that diagenetic evolution of reservoir rocks would be out of harmony with hydrocarbon generation history. The result led to many oil and gas layers, with irregular, dispersed and uneven distribution for oil and gas, and no water produced.
