摘要(Abstract)：

根据岩心、钻井、测井、薄片分析等资料,采用沉积学、岩石学与成岩作用分析结合的方法,研究黄龙场地区飞仙关组储层特征及储层分布主控因素。结果表明:黄龙场地区储层岩性以鲕粒云岩、粉晶化的鲕粒云岩和鲕粒灰岩为主,储集岩类型、储渗空间类型及储层物性呈现明显的东西区带分异的特征。飞仙关组沉积期东高西低的古地貌,导致东西沉积相带差异明显,是形成东部台地边缘鲕滩有利储层的关键;压实、压溶作用是造成储层减孔的主要原因;早期胶结、充填与初期压实的配置关系对原生孔隙的保存意义重大;白云岩化形成的晶间隙是东部有利储层形成的重要因素;断裂—裂缝系统及埋藏溶蚀作用的发育,对西部不具先期孔隙层的非相控型储层的改造有限。该结果为川东北黄龙场地区飞仙关组未来勘探开发提供指导。
