| 摘 要： | 苏里格气田是鄂尔多斯盆地上的重要气田,尤其是盒_8段为其主要的产气层段。根据分析,盒_8储层以中粗粒石英砂岩、岩屑石英砂岩、岩屑砂岩三种岩石类型为主,通过岩心分析得到储层孔隙度范围为3.05%～21.84%,渗透率一般在0.02～12.87 mD之间,含气饱和度平均值为60.8%。根据储层特征及参数分析,为了更好的对气井产能进行评价,将气井根据储层特征参数结合储层静态物性分为Ⅰ、Ⅱ、Ⅲ三类,便于气井稳产、配产的研究。

| Abstract: | Sulige gas field is an important gas field in Ordos Basin.Much gas was found in he_8 segment.By analysis,reservoir stone of he_8 segment are three main rock types,coarsegrained quartz sandstone,lithic quartz sandstone,lithic sandstone.It's prosity is 3.05%～21.84%;permeability is 0.02～12.87 mD;the average value of Sg is 60.8%.By the analysis of the reservoir characteristics and parameters,in order to better evaluate the capacity of gas wells,according to characteristics of the reservoir parameters in combination with the static properties,gas wells are divided intoⅠ,Ⅱ,Ⅲthree categories,is conducive for well stable production,and the research of its production. |
