Abstract: The source rocks in Binbei area are characterized by high organic matter richness and low maturity,and the strata are in the state of poor compaction.So it is vitally important for evaluating Binbei area to make sure whether hydrocarbon source rocks are available or not,and to fully understand how much oil and gas has been expulsed.This research implements a new method,hydrocarbon generation potential,to study the hydrocarbon expulsion characteristics in Binbei area.Taking hydrocarbon accumulation system as evaluating unit,analogy method is used to calculate the accumulation coefficient.On the basis of the accumulation coefficient,hydrocarbon accumulation systems are evaluated quantitatively,and then the favorable area is forecasted.

Key words: hydrocarbon source rock, hydrocarbon generation potential, hydrocarbon expulsion characteristic, hydrocarbon accumulation system, Songliao Basin
