摘要
为进一步认识英旺油田地质特征,文中以龙38-双6井区小层长821为例,分别从储层岩石学特征,储层物性及孔隙结构特征,储层非均质性等方面对其进行了研究。结果表明,长821储层岩石以细粒岩屑长石砂岩为主,填隙物主要以绿泥石粘土矿物为主,储层物性较差,层内非均质性中等偏强,属低孔、超低渗储层。
In order to further know the geological feature of Yingwang oilfield,taking Chang 821reservoir in Long38-Shuang6 well area as an example,its reservoir feature was studied from the aspects of reservoir petrologic feature,reservoir physical feature,pore structure feature,and reservoir heterogeneity feature.The results show that the Chang821 reservoir rock mainly is fine-grained lithic arkose,its interstitial material mainly is chlorite,its reservoir physical feature is very poor,layer heterogeneity is medium to strong,and belongs to low porosity,low permeability reservoir.
