摘要
浊沸石作为自生铝硅酸盐矿物,其析出、胶结和溶蚀对储层物性具有重大的影响。选取新疆油田某井区上乌尔禾组岩心样品进行孔、渗测试及全岩矿物分析,得到不同样品的浊沸石含量及相对应的孔隙度、渗透率等物性参数并分析其和浊沸石之间的关系;通过对铸体薄片研究分析浊沸石对孔隙结构及孔隙类型的影响。
As an authigenic aluminosilicate mineral,the precipitation,cementation and dissolution of laumontite have great influence on the physical properties of the reservoir.In this paper,the core samples of upper Wuerhe formation in a well area of Xinjiang oil field are selected for pore and permeability test and whole rock mineral analysis,and the content,porosity,permeability and other physical parameters of different samples are obtained,and the relationship between them and laumontite is analyzed;secondly,the influence of laumontite on pore structure and pore type is analyzed through the study of casting thin section.
