酸液浓度和总铁含量应该在操作中每小时检查一次。
Acid strength and total iron shall be determined every hour during operation from outlets.
为缩短酸洗时间，提高酸液温度的效果比增大酸液浓度的效果更好。
For shortening pickling time, improving pickling temperature is more significant than increasing hydrochloric acid concentration.
但短岩心酸化流动试验结果为：加大酸液浓度和用酸强度有利于提高酸化效果。
However, according to short core acid flow testing, higher concentration acid is helpful to increasing permeability.
