摘　　要：根据岩心铸体薄片、扫描电镜及物性等资料,研究杨米涧—大路沟地区长6储层的岩石学特征、物性特征、孔隙类型及孔隙结构。结果表明:研究区长6储层以长石砂岩为主,有少量岩屑长石砂岩;以次生溶蚀孔隙为主,主要发育长石溶孔和浊沸石溶孔;主要发育缩颈型、片状和弯片状喉道。分析认为研究区储层特征主要受到沉积作用和成岩作用的控制,溶蚀作用形成的次生孔隙构成本区最为主要的储集空间。Based on the data of casting lamella,SEM and physical analysis,the petro logical characteristics and physical characteristics,the types and structure of pore are studied. The results show that the sandstone of the reservoir is mainly composed of feldspathic sandstone,and little lithic feldspathic sandstone. And the pore types of the reservoir are mainly secondary porosity,which mainly compose feldspar dissolution porosity and laumontite dissolved pores; the throat types are mainly constriction throat and flaky throat. The primary influencing factors of the physical properties in the reservoir are sedimentary microfacies and digenesis,and the dissolution is the most important digenesis.
