HF酸是一种可溶解有害粒子的酸,在向地层渗透的过程中,HF也溶解原生粘土和长石,还在与石英的反应中被消耗一部分,使它的渗透受到明显的限制,而增加酸液的注入量又将导致地层,特别是松散地层的软化和出砂。因此在酸化作业中,传统的 HF acid, an acid that dissolves harmful particles, dissolves primary clays and feldspar during permeation into the formation and is also partially depleted in reaction with quartz, rendering its infiltration significantly restricted In turn, increasing the amount of acid to be injected will in turn cause softening and sanding of the formation, especially the loose formation. So in the acidification operation, the traditional
