摘　　要：通过岩心、薄片、扫描电镜观察、压汞分析，结合孔隙度、渗透率等物性资料，研究临江地区扶余一杨Ⅰ油层储集空间类型和主控因素．结果表明：临江地区扶余一杨Ⅰ油层为中低孔低渗的碎屑砂岩储层，孔隙度为10．0％～15．0％，渗透率为（0．01～10．00）×10^-3μm^2；砂岩发育原生孔隙和次生溶蚀孔隙2种储集空间类型，以次生溶蚀孔隙为主；储层孔隙结构不均匀，以小孔喉为主；储层物性主控因素，前期为沉积条件和埋深，后期为溶解作用和胶结、交代作用．研究结果对认识临江地区扶杨油层储层特征及主控因素有参考意义．Through careful core observation,normal and casting thin section,scanning electron microscope,mercury intrusion analysis combined with the area porosity,permeability and other physical data,the type space of the reservoir and the major control facorts of Fuyu-Yang Ⅰ reservoir to Linjiang area were studied.Research shows that Fuyu-Yang Ⅰ reservoir is a set of medium-low reservoir porosity and low permeability of clastic sandstone reservoirs,porosity and permeability values average is 10.0%～15.0% and(0.01～10.00)×10-3 μm2,and the sandstone reservoir of Linjiang region presents two space types,namely primary pores and secondary pores,mainly by secondary dissolution pores.Application of mercury intrusion method research shows that reservoir pore structure is uneven,mainly to small holes throat.Early in sandstone reservoir property controlling factors for sedimentary conditions and buried depth,later period mainly is dissolved function and strong cementation,metasomatism role.
