| 摘 要： | 在南堡凹陷大连片三维地震解释成果的基础上,对南堡凹陷新近纪的扭动构造特征、成因机理及其与油气聚集的关系进行了分析。南堡凹陷在古近纪伸展断陷的基础上,在新近纪发育了八个扭动断裂构造带,断裂组合平面上以雁列式、"帚状"、"入"字型为特征,剖面上以"负花状"、"半花状"、"X"型为主。晚期扭动断裂的发育既具有继承性,也有新生性。扭动断层在活动早期控制了生油次凹的发育,晚期控制了断鼻、断块的发育,同时断层的多期活动成为油气运移的良好通道,因此扭动断裂构造带是南堡凹陷新近纪油藏的主要富集区带。

| Abstract: | The characteristics and formation mechanism of the Neogene shear structures in the Nanpu sag and their controls on hydrocarbon accumulation are studied in this paper based on regional 3-D seismic survey. Following the extension in Paleogene,eight shear structure belts developed in Neogene within the Nanpu sag,which occur in echelon,broom or "入" patterns on the surface,and exhibit as negative flower-like,semi-flower-like and "X"-type occurrences in seismic profiles. The Neogene shear faults control the development of oil-generating sub-sag in the early formation stage of the Nanpu sag and the late stage development of the fault noses and fault block. The multi-phase activities of the faults supplied channels for oil and gas migration. Therefore,the Neogene shear structures are the main hydrocarbon accumulation belts in the Nanpu sag. |
