摘要: 研究分析发现松辽盆地滨北地区虽然有机质丰度高,但有机质的成熟度偏低,而且该区地层普遍欠压实。应用排烃门限理论,使用生烃潜力法对滨北地区中浅层的烃源岩排烃特征进行研究,指出该区有效烃源岩的层位、排烃门限深度和有效烃源岩分布面积以及排烃量的大小。结合滨北地区实际成藏地质条件,以油气成藏体系作为评价单元,应用类比法合理选择聚集系数,对各成藏体系进行定量评价,从而预测出最有利的勘探区带。

关键词: 烃源岩, 生烃潜力, 排烃特征, 油气成藏体系, 松辽盆地

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
