摘要
本文进行了1 9FNMR研究砂岩基质酸化的可行性实验 ,证明1 9FNMR是研究铝、硅氟化物平衡和HF、H2 SiF6同铝硅化物反应程度的有力手段。实验显示同一酸液配方在不同温度条件下及在相同温度、不同反应时间下所形成的氟铝、氟硅配合物种类是不同的 ,只有应用1 9FNMR才能鉴别出来。
This is a preliminary study on sandstone matrix acidization by using the 19 F NMR method. The reaction mixtures of koalinite with H 2SiF 6, of bentonite with HCl+HCl, and of a reservoir core with HCl+HF at different conditions are analysed by 19 F NMR for species of fluoro complexes of Al and Si and it is shown that the complex species formed at different temperature or in different reaction time are different.
