Abstract:

Different paleo uplifts in Sichuan Basin formed in differnt geological ages.The uplifts formed in Caledonian period are complicated in distribution;the one formed in Hercynian Indosinian period is Kaijiang inherited paleo uplift;Luzhou paleo uplift formed in Indo sinian is the front zone of west Sichuan foreland basin;the Jiangyou Mianzhu and Daxing Uplifts extened towards depression.These uplifts did not only reformed reservoir property,their traps also provided the site for hydrocarbon accumulation in the early stage,and favourable for oil and gas pool forming.So it is suggested that the paleo uplifts in Sichuan Basin are important realms for oil and gas exploration.

Key words: paleo uplift, initial hydrocarbon accumulation, Caledonian movement, Yenshan movement, Indo sinian movement, Sichuan Basin
