摘要
通过对滨南地区地层超覆油藏的区域地质特征、圈闭特征、油气运聚模式和分布规律的研究,提出了在断-拗过渡期构造-沉积体系中,复合疏导体系及其与优质烃源岩和构造背景在成油期的有机配置关系是地层超覆油藏油气运聚的主要模式,大型地层超剥带和继承性鼻状构造带的结合部位是寻找大中型地层油藏的主要方向。地层超剥带地震描述技术的运用,指导了该区地层超覆油气藏的勘探。
By studying regional geology characteristics, trapping characteristics, the mode of hydrocarbon migration and accumulation, and the oil-gas distribution in the strati-graphic overlap oil reservoirs of Binnan region, in the structure-sedimentation system during fault-sag transition period the compound translocation systems and its organic matching relationship between good - quality source rocks and structural background during the period of petroleum generating were the main mode of hydrocarbon migration and accumulation in the strati-graphic overlap oil reservoirs. The main direction of seeking middle-large stratigraphic oil reservoirs is the binding site of large stratigraphic ultra - denudation zones and inherited nosing structure zones. Application of seismic description technology to stratigraphic ultra -denudation zones guides the exploration of stratigraphic overlap hydrocarbon reservoir in this region.
