摘　　要：鄂尔多斯盆地南缘X区域长8储层分布广泛。针对储层非均质性以及主要影响控制因素认识不清的问题,从宏观和微观非均质性两方面研究。最终认为长8储层呈现强非均质性特点,同时还研究不同沉积微相与储层物性的关系;砂岩不同碎屑组分与储层孔隙度和渗透率的关系,其非均质性强的主控因素主要受沉积微相和砂岩碎屑组分两方面影响。The Chang 8 reservoir in the X area of the southern margin of the Ordos Basin is widely distributed.Aiming at the problem of reservoir heterogeneity in this area and the unclear understanding of the main factors affecting control,the macro and micro heterogeneity were studied.Finally,it is believed that the Chang 8 reservoir is characterized by strong heterogeneity,and the relationship between different sedimentary microfacies and the physical properties of the reservoir is also studied;the relationship between the different clastic components of sandstone and the porosity and permeability of the reservoir,its heterogeneity The strong main controlling factor is mainly influenced by sedimentary microfacies and sandstone clastic components.
