| 摘 要： | 青海南翼山油田卤水是高钙含硼盐卤体系，蒸发过程中硼的行为与已往报道的高镁含硼盐卤体系有较大不同，蒸发过程中不外加试剂就可自然结晶析出硼酸。研究分析证明，油田卤水体系硼的特殊结晶行为与体系pH值变化密切相关。

| Abstract: | Oilfield brine in Nanyishan district, Qinghai province, is high calcium and boron-containing brine system. According to former research, crystallization behavior of boron in this system is very different from that of high magnesium boron-containing brine systems. Boric acid can crystallize spontaneously without any external reagent in this system. Our investigations reveal that the pH change is the key factor for this special crystallization behavior of boron in this system. |
