| 摘 要： | 通过总结前人研究结果,利用测井、钻井地质和地化等资料,对冀中坳陷潜山油气藏类型和油气输导体系特征进行研究,并结合已发现的潜山油气藏,建立了不同油气输导体系与潜山油气藏类型的匹配关系。结果表明:根据不同的圈闭遮挡条件,可将冀中坳陷潜山油气藏分为潜山顶、潜山坡和潜山内幕油气藏等3种类型;潜山油气输导体系发育断裂、不整合、内幕溶蚀层和复合型输导体系等4种类型;受碳酸盐岩地层、断层活动性影响以及与油气生成时间的匹配,断裂型输导体系具有高效性和时效性的特征,有利于形成潜山顶和内幕油气藏;不整合型输导体系由不整合上部底砾岩和下部淋浴带组成,具有"双层"输导的特点,有利于形成潜山顶和潜山坡油气藏;内幕溶蚀层型输导体系由潜山内部的溶蚀孔-洞-缝系统组成,其发育程度受内部地层泥质含量控制,有利于形成潜山内幕油气藏;复合型输导体系由单一型输导体系复合形成,具有"多样式"的特点,可以形成潜山顶、潜山坡和潜山内幕油气藏。
