| 摘 要： | 准噶尔盆地东部下侏罗统三工河组孔隙类型：主要有剩余原生粒间孔和次生孔隙。剩余原生粒间孔是成岩早期淀粘主石英加在形成的，它们围绕屑边部分布。本地区，在剩余原生粒间孔发育的茂盛上、发生溶蚀作用，形成一些原生扩大孔，超大孔、粒内溶孔等。成岩早期胶结作用形成剩余原生粒间孔，晚期的溶蚀作用形成次生孔隙。

| Abstract: | Based on the study of diagenesis two types of pore in Sangonghe Formation of Lower Jurassic in Zhungaer basin have been recognized. They are mainly residue original interganular pore and secondary pore. Residue original intergranular pore has been preserved by the authigenic clay minerals and quartz overgrowth. Enlarged pore, oversized pore and intragranular pore have been developed on the base of residual original intergranular pore by the dissolution of framework constituents. Residual original intergranular pore developed during early diagenesis of sandstone, secondary pore was created by dissolution in late diagenesis. |
