| 摘 要： | 文章通过常规物性分析和特殊岩心分析，对鄂尔多斯盆地北部下奥陶统马家沟组地层的储集物性进行了研究。指出了储集物性在纵向上的变化规律，并从岩心测试的角度提出了天然气在该套储层中作有效运移的最低孔隙度和获取工业气流所必需的孔隙度下限值。

| Abstract: | Based on the conventional petrophysical property analysis and special core analysis, the reservoir petrophysical properties of the Majiagou Formation of Lower Ordovician in the northern part of Ordos Basin are studied in this paper. The vertical variation regularities of petrophysical property are also indicated. From the viewpoint of the teSt,the lowest porosity for the effective migration of gas in the reservoir rocks and the cutoff value of the effective porosity for acquiring commercial gas production from the reservoir rocks are presented in this paper. |
