| 摘 要： | 酸化夹石膏地层时,石膏会溶于盐酸。随着酸化的进行,酸液浓度降低,氯化钙浓度增加,因而产生了石膏的再沉淀现象、本文通过石膏在盐酸、氯化钙水溶液及余酸中的溶解度讨论了酸化时石膏的再沉淀现象,并提出了防止石膏再沉淀的方法

| Abstract: | Gypsum can dissolve in hydrochloric acid when gypsum-containing formation is acidized. During the acidizing operation, the concentration of acid solution decreases and the concentration of calcium chloride increases, the secondary precipitation of the gypsum appears. In this paper, we discuss the secondary precipitation of the gypsum by the solubilities of the gypsum in hydrochloric acid and calcium chloride solution and in spent acid during acid treatment. We also propose the methods of its prevention. |
