【摘要】 选择了克拉玛依油田二中区Ｔ２ ｋ１ 砂砾岩储层中的六种储层矿物：石英，正长石，微斜长石；Ｃａ蒙脱石，高岭石，伊利石。在不同的条件下研究了这六种矿物的碱耗量，还研究骨架矿物与粘土矿物按照一定的质量配比而成的复配矿物的碱耗量，探讨了矿物碱耗的协同效应。结果表明单矿物的碱耗序列为：蒙脱石（Ｓ）＞ 高岭石（Ｋ）＞ 伊利石（Ｉ）＞微斜长石（Ｍ）＞ 石英（Ｑ）＞ 正长石（Ｊ）。复配物的碱耗总体上受粘土矿物控制，尤其是蒙脱石的加入明显提高了复配物的耗碱量。但是粘土矿物的加入并不改变骨架矿物的碱耗序列，骨架矿物的加入也不改变粘土矿物的碱耗序列更多还原

【Abstract】 Six types of reservoir minerals, such as quartz, orthoclase, microcline, montmorillonite, kaolinite, illite, are selected to study their alkali consumption in various conditions, to investigate the alkali consumption of clay minerals mixed with grain sized minerals at different ratios and to discuss the co effect of alkali consumption of minerals. Present results show that the sequence of alkali consumption of these monominerals is characterized by montmorillonite>kaolinite>illite>microcline>quartz>orthoclase. The alkali consumption of mixed minerals is generally controlled by clay minerals. For instance, the addition of montmorillonite increases the alkali consumption of mixed minerals considerably. However the addition of clay minerals does not change the sequence of alkali consumption of grain sized minerals and similarly, the addition of grain sized minerals does not change the sequence of alkali consumption of clay minerals.更多还原
