运用岩心、铸体薄片、扫描电镜和分析化验等资料，系统研究了柴达木盆地北缘鱼卡—九龙山地区侏罗系储层孔隙结构特征，并对其储层发育的控制因素进行了分析。 结果表明：研究区侏罗系储层储集空间为原生粒间孔、溶蚀孔和少量裂缝，其中，溶蚀孔占较大比重，对改善该区储层物性具有重要的作用；成岩作用对储层的储集性能影响较大，成岩作用强度，特别是胶结作用和溶蚀作用的发育程度对鱼卡—九龙山地区侏罗系储层物性影响较大。

By means of cores, cast thin sections, scanning electron microscope and testing data, this paper studied the reservoir pore structure characteristics of Jurassic in Yuka-Jiulongshan area in northern margin of Qaidam Basin, and analyzed the controlling factors of reservoir development. The result shows that the reservoir spaces in the study area are mainly primary intergranular pores, dissolved pores and microfractures, among which dissolved pores are dominated and play important role in improving the reservoir properties. The reservoir mainly experienced such actions as compaction, cementation and dissolution. Especially the cementation and dissolution are the main reason of generating the secondary pore in Yuka-Jiulongshan area.
