Abstract: The Carboniferous petroleum system, with its formation and evolution largely controlled by the regional structural evolution, is one of the confirmed petroleum systems in eastern Sichuan Basin. The pool-forming history of this petroleum system can be divided into two stages. The first stage is from
the Indosinian orogeny at the end of middle Triassic to pre-Himalayan movement, during which constant hydrocarbon accumulation towards the Kaijiang paleohigh occurred against a background of continuous growth of the paleohigh, resulting in the formation of areally extensive stratigraphic-structural combination pools within the Carboniferous strata. The second stage started in early Himalayan at the end of Oligocene, during which post-accumulation re-distribution of hydrocarbons took place to have formed the stratigraphic-structural combination pools and anticlinal pools on the Kaijiang paleohigh.

Key words: Carboniferous, petroleum system, pool -forming, evolution, Sichuan Basin
