| 摘 要： | 为了深化西湖凹陷浙东中央背斜带油气成藏过程的研究，优化勘探目标选择，在烃源岩特征分析的基础上，应用动态数值模拟技术，定量恢复了研究区主要烃源岩层系的生排烃历史，研究表明，浙东中央背斜带主要发育4套烃源岩系，其中始新统平湖组泥岩与煤层为主力烃源岩，具较高的有机质丰度=生烃强度与排烃效率，烃类排出具阶段性、多期次幕式排烃的特点汉平湖组为源岩的油气系统应是本区油气勘探的主要目标。

| Abstract: | In order to deepen the research of hydrocarbon accumulation process and choose the optimum exploration targets,the hydrocarbon generation history and expulsion history in the Zhedong central anticline belt were reconstructed quantitatively by use of the technique of dynamic numerical modeling,based on the analysis of source rock characteristics.It is shown that there are four source rocks in the study area,that the Eocene Pinghu Formation is the principal source rock,which had a high organic matter abundance,hydrocarbon generation intensity and hydrocarbon expulsion efficiency,that the process of expelled hydrocarbon appeared in multi stages and multiperiods,and that the petroleum system from the Pinghu Formation source rock should be the major exploration target in the study area. |
