【摘要】 济阳坳陷垦东凸起紧邻郯庐断裂带西支断裂,走滑活动强烈,垦东断层南段及其NE向的延伸和发育于潜山主体带与东部斜坡带交界处的浅层走滑构造带是研究区内主要的2条走滑构造带。通过对贯穿2条走滑构造带的地震剖面和时间切片的精细解释,以及对走滑构造平面和剖面上不同的几何学特征的分析,将研究区内的走滑构造分为成熟型和隐伏型2种。在对走滑构造特征分析的基础上,结合研究区内的油气分布和成藏特征,进一步探讨了不同时期的走滑活动对研究区内的油源、油气运移和输导、油气藏的形成和保存等方面的影响。更多还原

【Abstract】 Kendong area is located close to the west branch fault of Tan-Lu fault zone and strike-slip motion behaves intensely there. The south segment of Kendong fault with its NE extension part and the shallow strike-slip zone between the Kendong buried hill and the east slope are the two important strike-slip zones in the study area. Based on the carefully interpreted seismic sections and time slices across the strike-slip zones, the strike-slip structural feature is further discussed. According to the different geometrical shapes in the horizontal and vertical sections, the strike-slip structure in the study area is divided into two styles: matured strike-slip zone and buried strike-slip zone. Based on the research result of the strike-slip feature in the study area, in combination with the oil and gas distribution and accumulation characteristics, this paper discussed the influence of the strike-slip motion on the reservoir resource, hydrocarbon migration, accumulation and protection at different epochs.更多还原
