摘要
近年来,国内地层油气藏的勘探已引起普遍关注。文章在前人研究的基础上,以不整合面为切入点,依据圈闭机制的不同,给出了地层圈闭新的划分方案,把地层圈闭划分为不整合面之上超覆型地层圈闭、不整合面之下遮挡型地层圈闭以及不整合面之间削截型地层圈闭。地层油气藏的形成与不整合强度、不整合结构有着密切的关系,文章从以上2个方面对地层油气藏的形成机制进行了分析。此外,文章还对不同类型地层油气藏的分布规律进行了总结,对其勘探提出了建议,并且指出了一些亟须发展的理论和技术。
The importance of stratigraphic reservoir exploration is rising day by day on the condition that the field of national oil and gas exploration is transferred from structural reservoir to litho-stratigraphic reservoir. On the basis of the former research, this paper centers on the unconformity and classifies the stratigraphic trap into three types： the on-lapping typed trap above the unconformity, the barrier typed trap below the unconformity and the truncation type of trap between the former unconformity and the later unconformity according to the difference of trap mechanism. This paper summarizes the formation mechanism of stratigraphic reservoir from the strength and the structure of the unconformity. Furthermore, authors point out the distribution law of different type of stratigraphie reservoirs and exploration suggestion for different type of stratigraphic reservoirs. Finally, this paper points out some theories and techniques which are in great need for stratigraphic reservoir exploration.
