摘　　要：志丹地区作为陕北的重要产油区之一,长6时期发育为三角洲前缘亚相,形成了以水下分流河道与河口坝为主要发育类型的沉积体系。生、储、盖条件良好,分选差,是远物源沉积形成的低孔、特低渗储层的典型油气藏。分析了本地区长6储层物性及岩石学基本特征,并在此基础上分析其影响控制因素,分析研究表明孔隙结构特征、沉积环境及成岩作用对储层物性特征起到了主要的控制作用。Zhidan region,as one important oil-producing area in Shanbei,having developed the delta front during chang6 reservoir,mainly formed the sedimentary system of underwater distributary channel and river dam.Having good storage conditions and poor sorting,it is a typical reservoir of low holes and low permeability.In this paper,physical properties of chang6 reservoir were analyzed as well as basic features of petrology,and various factors were discussed.The results show that main controlling factors to the reservoir characteristics are pore structure,sedimentary environment and diagenesis.
