摘要

摘要: 运用X衍射手段准确鉴定了石油储层中的碳钠铝石矿物,详细解析了其衍射曲线特征,这在我国尚属首次。研究表明,海拉尔盆地的碳钠铝石存在于火山凝灰岩或沉积凝灰岩中,常与柯绿泥石和钠板石共生,形成凝灰质蚀变的特征标型矿物组合。海拉尔盆地碳钠铝石矿物由典型的碱交代作用形成,因为火山凝灰物质易于在碱性条件下蚀变。碳钠铝石交代斜长石晶屑可形成对油气富集贡献很大的次生孔隙,构成某些地区的主体含油层段。

Abstract: The dawsonite in oil-bearing reservoir was identified accurately with X-ray diffraction method for the first time in China,and its diffraction characteristics was given in detail.Research shows that the dawsonite in Hailaer Basin exists in both the eroded volcano tuff and sedimentary volcano tuff,and is paragenous with corrensite and allevardite frequently.This paragenetic association is one of the typomorphic minerals of eroded volcano tuff and sedimentary volcano tuff.The dawsonite in the Hailaer Basin forms by typical alkaline metasomatosis,because the volcano tuff is easily eroded under the alkaline conditions.The plagioclase alkaline metasomatosis by dawsonite results in the formation of the secondary porosity contributing to the hydrocarbon accumulation,which constitutes dominating oil-bearing reserver in some regions.
