【摘要】 冀中坳陷牛驼镇凸起南段潜山具有含油层系少、勘探程度低的特点。对潜山油源、储盖组合、油气输导体系、圈闭类型等的研究结果表明,牛驼镇凸起南段潜山具有良好的油气成藏条件,发育有潜山风化壳和潜山内幕2种类型的油气成藏模式,不同的模式具有不同的油气运聚特征。分析认为,牛驼镇凸起南段潜山具有良好的勘探潜力,其中雄11井北潜山残丘圈闭和霸28井潜山内幕圈闭是该区下步扩大潜山残丘勘探规模和获得潜山内幕勘探突破的首选目标。更多还原

【Abstract】 The buried hill in southern Niutuozhen uplift of Jizhong Depression is characterized by little oil-bearing series and low degree of exploration. The oil sources, reservoir-seal assemblage, migration system and trap types of buried hill are studied. The result shows that the buried hill in southern Niutuozhen uplift has favorable hydrocarbon accumulation conditions, and developed two types of hydrocarbon accumulation models, including weathered crust of buried hill and inner buried hill, and different model has different characteristics of hydrocarbon migration and accumulation. It is believed that the buried hill in southern Niutuozhen uplift has favorable exploration potential. The buried hill monadnock trap in northern Xiong 11 well and the inner buried hill trap in Ba 28 well will be the next preferred exploration targets.更多还原
