王庄地区超覆油藏勘探研究

Exploration of overlapped oil reservoirs in Wangzhuang area

通过对王庄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研究, 提出了在断—坳过渡期构造沉积体系中复合疏导体系及其与优质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等观点, 运用地层超剥带的地震描述技术指导了王庄地区地层超覆油气藏的勘探开发工作。

Through studies on regional geology characteristics,trap feature,petroleum migration model and the distribution law of stratigraphic overlapped oil reservoirs in Wangzhuang area,the following viewpoints are presented: the organic allocation of composed penetration system with fine source rock and structural setting in oil generation period is the main model of migration and accumulation of stratigraphic overlapped petroleum reservoirs,the former exists in fault-depression transition period and in structure-sedimentation system; the combined part between large-size stratigraphic overlapped and stripped belt and progressive nose-like structural belt is main favorite direction to seek for large and medium size stratigraphic oil reservoirs and so on. Seismic description technique applied in stratigraphic overlapped and stripped belt has guided the exploration and development of stratigraphic overlapped oil/gas reservoirs in Wangzhuang area.
