摘要
渤海湾盆地断陷湖盆的斜坡带是油气聚集的重要场所。通过对廊固 武清凹陷构造演化历程分析 ,确定了杨村斜坡的形成演化过程。杨村斜坡不具有相邻文安斜坡“深沟高垒”式的垒嵌结构 ,而是一个相对简单的单斜。从斜坡成因机制上解析了垒嵌结构与单斜地质结构差异的形成原因。根据杨村斜坡的单斜地质结构特征 ,其成藏模式应以地层
The slope belts of rifted lacustrine basin in Bohai Bay Basin are very important for hydrocarbon accumulation. The structure evolution in Langgu-Wuqing Depression was analyzed. The difference between Yangcun Slope and Wenan Slope was discussed. The Wenan Slope was characterized by the structure of deep channel and high horst, while the Yangcun Slope showed a relative simple monoclinic. The difference can be explained with genetic mechanism. According to the simple monoclinic characteristics of the Yangcun Slope, the stratigraphic and lithologic oil and gas pools may be the main accumulation model.
