摘要: 主要从断裂系统、构造圈闭类型、地层分布、接触关系、砂体类型及基岩等6个方面阐述了我国东部古近系—新近系箕状断陷的石油地质特征及油藏类型。论述了深陷带不仅是生油区,而且是储油区。分析了断陷盆地由单断型和双断型两种凹陷组成,每个单断凹陷可分为陡坡带、深陷带和缓坡带3个次一级构造单元。重点论述了在没有大型潜山带和二级构造带的深陷带中,各种隐蔽油气藏的形成条件及展布规律。

Abstract: This article elaborates the petroleum characteristics and reservoir types of the Paleogene-Neogene half graben-like rifts in the eastern part of China mainly in terms of six aspects-fault system, types of structural trap, distributed formations, contact relations, types of sand body, and basement. Deep sag belt is elaborated not only as sourcing area but also as reservoir area. Based on the analysis, rift basin is divided into single-rift type and dual-rift type. Each single-rift depression can be divided into three secondary structural units-steep slope belt, deep sag belt and gentle slope belt. The article focuses on the development conditions and distribution laws for various subtle oil and gas reservoirs in deep sag belts where there are no l
