| 摘 要： | 从微观到宏观研究了盖层封闭特征，从垂向和侧向两个方面研究了断层的封闭特征，通过古流体势场恢复，研究了本区油气运聚形式。根据封盖条件、生储特征、运移特征，将延吉盆地东部坳陷划分了三个油气运聚系统，即德新地区封闭型运聚成藏系统、广兴—东风地区半封闭型油气运聚系统、延吉—东盛涌地区油气逸散系统。在油气运聚系统划分的基础上，对有利探区进行了预测。

| Abstract: | The present paper studies the micro characteristics and macro characteristics of caprock seals, the lateral and vertical characteristics of fault seals, and the styles of hydrocarbon migration and accumulation through the reconstruction of paleofluid potential field. Three hydrocarbon syotems, i.e. the sealing system of hydrocarbon accumulation in Dexin Area, the semi-sealing system of hydrocarbon accumulation in Guangxing-Dongfeng Area, and the unsealing system of hydrocarbons in Yanji-Dongshengyong Area, are recogized in the east depression of Yanji Basin. Based on the different syotems, the favourable areas for hydrocarbon accumulation are further predicted. |
