摘　　要：通过铸体薄片、扫描电镜、物性资料以及岩心照片分析,对研究区长6致密储层特征及其主控因素进行深入研究。研究结果表明,正宁地区长6致密储层主要受沉积微相、填隙物含量、压实作用、胶结作用及裂缝发育水平等因素的综合影响。此外,储层物性与含油性具有明显的正相关性,局部发育的优质储层是油井高产的重要原因。Based on the thin sections,scanning electron microscope,material data and core photos of Chang 6 formatiion in Zhengning area,the tight reservoir characteristics and main controlling factors are investigated. The results show that sedimentary microfacies,interstitial fullings,intense compaction,cementation and fractures mainly control Chang 6 tight reservoirs in the research area. Furthermore,there is a positive correlation between reservoir physical property and oil content,and high-quality reservoirs which are developed locally also contribute to high yield of oil wells.
