| 摘 要： | 准噶尔盆地西北缘侏罗系陆相碎屑岩储层的岩性差异较大，岩性对物性的控制作用明显。储层的孔隙类型多样，不同类型的孔隙在发育规模、丰度及有效性方面都存在显差异，次生溶蚀孔隙、原生粒间孔隙和残余粒间孔隙是最重要的有效孔隙类型。储层渗透率与孔隙度之间存在较好的半对数相关关系。通过设置一定的孔隙度和渗透率参数界线，对储层储集性能进行评价，将侏罗系储层的孔渗性能划分为5个级别，可与当前流行的砂岩储层孔渗性能分级相对应。通过对大量压汞参数样本的聚类分析，将储层的孔隙结构划分为4个类型。通过各类参数统计及曲线形态对比，对孔隙结构类型进行了定量结合定性的优劣评价。最后，结合孔渗性能级别、储集空间类型、孔隙结构类型、岩性等特征，对准噶尔盆地西北缘侏罗系储层进行了综合分类评价。 |

| Abstract: | The reservoir rock types of Jurassic reservoir of the northwest edge in Junggar Basin are of apparent difference. The controlling effects of the reservoir rock types upon reservoir properties are also apparent. There are a few pore types in reservoir rocks, and the different pore types have the apparent differences with each other in some aspects, such as pore scale, abundance and effectiveness. The secondary solution pores, initial intergranular pores and residual intergranular pores are the most important and effective pores. A good linear relation exists between log permeability and porosity. Based on the relation, a series of certain limits are defined to evaluate reservoir properties. The 5 grades for porosity and permeability of the Jurassic reservoir are subdivided, which corresponds to the prevalent sorting grades of sand reservoirs to some extent. A number of samples of mercury injection parameters are analyzed. The pore texture can be subdivided into 4 types. The statistical parameters and typical curve shapes are contrasted, and the effectiveness of each pore texture type is quantitatively and qualitatively evaluated. Finally, the porosity and permeability grades, pore types, pore texture types and reservoir rocks are used to evaluate the Jurassic reservoir of the northwest edge in Junggar Basin. |
