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