摘要
柯绿泥石和钠板石为稀有矿物,在储集层中并不常见,而两者同时出现则很罕见.作者通过最近的海拉尔盆地特殊储层样品的X衍射试验分析和详细研究,发现1:1规则混合层矿物柯绿泥石和钠板石同时存在于海拉尔盆地含火山凝灰质蚀变储层或非储层的某些井段中,而且在一定范围内的岩石孔隙中可以大量持续出现,指出了本区柯绿泥石和钠板石的组合特征,结合该区地层水和微量元素地球化学特征以及重砂特征等研究了柯绿泥石和钠板石的成因矿物学意义和其它石油地质意义.海拉尔盆地柯绿泥石和钠板石在同一储层样品中的共生存在现象是世界范围内的首次发现和报道.
Corrensite and allevardite are seldom in reservers, and they appear very rare at the same time. The author analyses and studies in detail through X-diffraction test of up to date special reserver samples and find that 1 ： 1 regulation mix layers of corrensite and allevardite exists in some piecis of the eroded volcano tuff＇s sandstone at the same time, and can appear continuously in a large amount In a certain limit, authors point out characteristic of corrensite and allevardite in this district and it＇s mining to genesis mineralogy that related to stratum water and trace element geochemistry characteristics, The occurrence of co-existing corrensite and allevardite in the same reserver sample is a first discovery in the world.
