摘　　要：通过对大量铸体薄片、扫描电镜、孔渗测定、压汞资料和测井数据分析,认为红井子-马坊地区长8长9储层具有以下特征:研究区主要以岩屑质长石砂岩、长石质岩屑砂岩为主,并含少量岩屑砂岩。长9储层以长石砂岩为主,其次为岩屑质长石砂岩。孔隙类型长81主要以粒间孔和长石溶孔为主,长82则主要以粒间孔为主,长9以粒间孔和长石溶孔为主。对储层影响因素进行了分析。Through a large number of casting thin sectiona scanning electron microscopy, determination of porosity and permeability, mercury injection data and well log data analysia it is considered that the Chang 8 and 9 reservoir in Hongjingzi-Mafang area has the following characteristics：Study area mainly contains lithic arkose, feldspathic lithic sandstone, and a small amount oflithic sandstone. The Chang 9 reservoir contains mainly feldspar sandstone, followed by lithic arkose.For the pore type, it is mainly intergranular pores and feldspar dissolved pore in the Chang81, and the Chang82 based mainly intergranular pores, and the Chang9 to intergranular pores and feldspar dissolved pore. Factors on the reservoir were also analyzed.
