| 摘 要： | 通过对南襄盆地泌阳凹陷的测井资料、岩石薄片、铸体薄片、地球化学特征、粒度资料分析,详细研究了泌阳凹陷南部陡坡带南部桃园组三段碎屑岩体的储层特征。泌阳凹陷南部陡坡带南部核桃园组三段为一套扇角洲-湖泊沉积体系,储集砂体主要发育在扇三角洲前缘水下分流河道、河口砂坝、前缘席状砂体、湖底扇等沉积微相内。储集层的岩性主要为岩屑砂岩和长石岩屑砂岩,储集空间以原生孔隙为主,孔隙连通性较好,孔隙度平均值为10%～20%,渗透率平均值为1000×10-3μm2,属于中孔高渗储层。扇三角洲前缘滑塌成因的湖底扇沉积砂体物性较好,且被周围的浅湖-半深湖相暗色烃源岩包围,是该区核桃园组最有利的储集砂体。
