摘要:
济阳坳陷是中国东部重要的新生代油气资源生产基地,潜山油气藏是其重要的油气藏类型。中新生代构造 运动对潜山油气藏的形成机制及类型具有关键性作用。基于印支、燕山和喜马拉雅运动的动力学性质及构造响应 研究,综合不同地质历史时期构造演化特征,分析济阳坳陷潜山形成机制,探讨油气藏类型,发现印支、燕山和喜马 拉雅运动的共同作用使济阳坳陷具有“挤-拉-滑”成山机制,主要表现在地层不整合、背斜、逆断层、倒转构造、负反 转及雁形断层等挤压、拉张和走滑构造响应等方面。潜山油气藏的储层类型及分布与挤压、拉张和走滑运动密切 相关,根据储层特征和成藏主控因素将济阳坳陷潜山油气藏划分为地层类、断块类和复合类3大类,进而可细分为9 小类。

Abstract:
Jiyang Depression is an important Cenozoic oil and gas resource production base in eastern China,and the buried hill reservoir is an important reservoir type. The Mesozoic and Cenozoic tectonic movements play a key role in the formation mechanism and types of buried hill reservoirs. Based on the study of the dynamics of Indosinian movement,Yanshan movement and Himalayan movement and their tectonic responses,the formation mechanism of buried hills in Jiyang Depression was analyzed by synthesizing the tectonic evolution characteristics of different periods,and then types of reservoirs were explored. It was found that the combined actions of Indo-China movement,Yanshan movement and Himalayan movement make Jiyang Depression extruded,tensioned and strike-slipped,which is characterized by extrusion,tension and strike-slip structure responses such as unconformity of the stratum,anticline,reverse fault,inverted structure,negative reversal,and geese fault,etc. Reservoir type and distribution of buried hill reservoir are closely related to extrusion,tension and strike-slip movements. According to reservoir and reservoir control factors,buried hill reservoirs in Jiyang Depression are classified into 3 types including strata,fault block and compound reservoir,and can be further classified into nine subclasses further.
Key words:  pre-Cenozoic  extrusion  tension  strike-slip  reservoir type  buried hill  Jiyang Depression
