| 摘 要： | 通过岩心观察、薄片鉴定、物性分析和扫描电镜观察等技术手段,研究了松辽盆地红岗北地区扶余油层岩性油藏储层的沉积特征、岩石学特征、物性特征、孔隙类型、结构特征及成岩作用特征,并进一步分析了储层主控因素。研究结果表明:红岗北地区扶余油层岩性油藏储层主要是顺源带状展布的(水下)分流河道微相及河口坝微相砂体,岩性主要以长石岩屑砂岩、粉砂岩为主,属于低—特低孔、低—特低渗储层,成岩阶段处于晚成岩A2段。储层物性主要受控于成岩作用和沉积微相,压实和胶结作用使储层孔隙度大量丧失、物性变差,而溶蚀作用产生次生孔隙使储层物性得到改善;不同沉积微相类型的储层物性差异较大,分流河道微相和河口坝(或席状砂主体)微相是油气聚集的有利相带。
