摘要
通过对户部寨气田古近系沙河街组沙四段砂岩储层岩心的观察试验,从微观和宏观两个方面分别对气田裂缝的孔隙度、渗透率进行了计算,并依据计算结果,对裂缝性储层提出了三大类Ⅳ亚类的分类方案,最终确定户部寨气田沙四段砂岩储层为第Ⅳ亚类。
Through core observation analysis of sandstone reservoir of the Shahejie formation of Paleogene in Hubuzhai gas field,the porosity and permeability have been calculated from both microcosmic and macrocosmic aspects.Based on the calculated results,the reservoir classification plan on fractured reservoirs have been put forward and there are three classes andⅥsubclasses in all.In the end,the sandstone reservoir of the Shahejie formation is decided to beⅣsubclass.
