| 摘 要： | 根据大量的测井资料和铸体薄片、扫描电镜、粒度分析、压汞分析资料,对延长区长6储层特征及其主控因素进行了综合研究。研究表明：该区长6储层属中-低孔、超低渗储层,在成岩阶段后期的改造作用下,其储集条件明显变好,储集空间以粒间孔为主。储集能力格局的分布主要受沉积微相展布规律和成岩作用控制,局部发育的微观裂缝对改善储层物性有一定作用。储集性能在平面上以水下分流河道和河口坝砂体物性最好;垂向演化上受成岩作用控制,压实和胶结作用使储层物性明显变差,溶蚀作用产生的次生孔隙改善储层孔、渗性,形成有效储层。 |

| Abstract: | The main controlling factors of chang6 reservoir in Yanchang area are discusses through using the log information,testing and analytical information such as Casting section,scanning electron microscope,grain size analysis and penetration et al.The results show that Chang 6 reservoir belongs middle-low hole and ultralow reservoir.The collection condition get better up and storage space up giving first place to intergranular pore under the late diagenetic stage make over effect.The distribution storing the co... |
