摘要
HF与铝硅酸盐的反应一直被认为是十分简单的一步反应，但它的副产物氟硅化物和氟铝化物的后继反应却是十分复杂的，通过^(19)FNMR对各物种的分布情况的分析，可完全认识土酸酸化的实际溶液化学行为。本文简要回顾了砂岩酸化反应动力学的历程。介绍了近年来国外在这方面所作的最新研究成果。
Reaction of HF on aluminium silicate is always considered to be a simple one-step reaciton, but the succeed reaction of its by-product fluoro-silica compund and fluoro-aluminia compound is very complex. After analizing distribution of every species by ^(19)FNMR, the actual solution chemical behavior of mud acid is understood completely. This paper briefly reviews the kinetic mechanisms of sandstone acidizing reaction, and introduces the recent research achievements abroad in this aspect.
