摘要
分析了东濮凹陷石油地质条件 ,对深层重点勘探目标进行了评价与解剖 .从构造演化、大型封闭高压舱的形成及成烃演化条件三方面探讨了深层油气藏形成条件与成藏规律 ,进而分析了砂体分布、构造条件、次生孔隙发育带对深层油气藏的控制作用 ,认为东濮凹陷深层油气藏可划分为构造型、岩性型及两者相结合的混合型 ,其中构造型主要分布在隆起带 ,岩性型分布于洼陷中 .砂体的分布直接控制了油气藏的位置与规模 ;构造条件是油气的另一主要控制因素 ;次生孔隙发育带成为深层油气的有效储集空间 .这对东濮凹陷及相似地区深层油气勘探有着重要的指导意义 .
The petroleum geological condition and the deep exploration target in Dongpu depression were analyzed and evaluated. The forming condition and regularity of the oil and gas pool were discussed in three aspects such as structural evolution, large scale high pressure circled pool, and hydrocarbon generation evolution. The influence of distribution of sand body, structural condition, developed zone of secondary pores on the oil and gas pool are also analyzed. The result is of important significance for the exploration of deep oil and gas pool in Dongpu depression and the similar areas.
