渤海湾盆地南堡凹陷滩海区油气立体输导模式——以南堡1号构造带为例

Hydrocarbon Migration Pattern of Beach Region in the Nanpu Depression,Bohai Bay Basin——An Example of Nanpu 1 Structure Belt

为研究渤海湾盆地南堡凹陷滩海区油气输导体系,评价其输导能力,对南堡凹陷滩海区1号构造带典型油藏进行剖析,从骨架砂体的横向和纵向连通性以及断层在平面和剖面的输导特性入手,分析输导要素在时空上的配置关系,根据骨架砂体和断层在平面上的分布样式以及通源断层在剖面上的布局,提出了南堡凹陷滩海区油气"伞状"运移的立体输导模式。

In order to study the hydrocarbon migration system of beach region in the Nanpu Depression and evaluate its gas transporting ability, this paper analyzed the typical reservoir of beach region 1 structure belt and the relationship of migration elements in time and space based on the characteristics of skeleton sand bodies＂ connection and faults migration. According to distribution patterns of skeleton sand bodies in horizontal and faults of communicating source rocks in vertical, the authors put forward the ＂umbrella shape＂ migration pattern with three-dimension at beach region in the Nanpu Depression.
