济阳坳陷缓坡带构造特征及分类

对济阳坳陷缓坡带地区进行构造分类研究,提出以基底断裂发育程度、后期活动与下第三系同沉积断层的组合特征作为断陷盆地缓坡带类型划分标准的“成因-结构”分类方式,将缓坡带划分为单断型与双断型缓坡带两大类以及坡折式、断阶式、垒堑式和半地堑式缓坡带4种类型。结合每一种类型的缓坡带形成的地质环境及对油气成藏的控制作用,总结出4种不同的油气运聚成藏模式。

Structural Features and Classification of the Gentle Slope Zone in Jiyang Depression

The structural pattern to the the gentle slope belt of Jiyang depression is classified, and put forwards the combination character of the development extent of the basement rift and the last stage activity and the early tertiary fault with sediment as the classification criterion. This is the first time that the gentle slope is classified into two big categories according to the "genetic texture": single rift and double rift gentle slope, which it is also classified into four types in detail: slope break, piece wise rift, horst graben and half graben. Summarized four different oil and gas reservoir migration and concentration formation models combining the geological environment forming every kind of the gentle slope and the controlling function to oil and gas reservoir formation.
