利用盐酸、醋酸及它们的混酸对富碳酸盐油田设备管垢进行清洗研究 ,讨论了酸的浓度、温度及添加剂对其溶垢能力的影响 .结果表明 ,盐酸具有很强的溶垢能力 ,反应剧烈 ,对金属腐蚀大 ,需要其它添加剂配合使用 ;醋酸在室温下溶垢能力小 ,在较高温度下才具有较好的除垢性 ,使用时浓度不宜过大 . Hydrochloric acid, acetic acid and their mixed acid were used to purge the scale in carbonate-rich oilfield equipment. The effects of acid concentration, temperature and additives on their scale-dissolving ability were discussed. The results showed that hydrochloric acid had strong scale- Severe reaction, the metal corrosion, the need for other additives used in conjunction; acetic acid at room temperature, small scale solubility, at higher temperatures, have good detergency, concentration should not be too large.
