准噶尔盆地南缘东段二叠系、三叠系以及侏罗系大面积分布碎屑岩储集层,其沉积环境多变,非均质性明显。野外观察以及(铸体)薄片等分析研究表明,研究区储层属(特)低孔、(特)低渗性储层;孔隙类型以粒间溶孔为主;喉道类型以片状、弯片状以及管束状喉道为主。进一步研究表明,研究区侏罗系储层以型与型为主,三叠系储层以、型为主,而二叠系以型为主。

There are large areal clastic reservoirs in the Permian,Triassic and Jurassic i n eastern part of southern margin of Junggar basin. The sedimentary environment  changed frequently and the anisotropy of the reservoir is apparent. Field observ ation and (cast) thin-section analysis indicate: The intergranular dissolved po re is the main pore type and the throat type is mainly of sheet,tortuous sheet a nd bundled tubes. The result of the successive research indicates: The type of r eservoir in Jurassic is mainly ofⅠandⅡ,and in Triassic is mainly of Ⅱ and Ⅲ,  the reservoir in Permian is mainly of Ⅲ.
