| Abstract: | In order to deepen the research on hydrocarbon accumulation process and choose the optimum exploration targets, the hydrocarbon generation and expulsion history in the Chagan Sag had been restored quantitatively by applying the technique of numerical modeling dynamically, based on the analysis of source rock characteristics. It is shown that there are three source rocks in the study area: that the Second Member of Bayingebi Formation is the principal source rock, which had a high of organic matter abundance, hydrocarbon generation intensity and hydrocarbon expulsion efficiency; that the process of hydrocarbon expelled appeared multi-stages and multi-periods; and that the petroleum system from the Second Member of Bayingebi Formation source rock should be the major exploration target in the study area. |
