摘　　要：原油盐含量测定是原油评价中非常重要的数据。论述了电位滴定法测定盐含量的优势及注意事项。电位滴定法与指示剂滴定法相比,是由仪器主动确定滴定终点,数据准确度更高。电位滴定法与电量法相比,取样量大,数据有良好的代表性。在作为仲裁方法或与国际贸易接轨时,宜选用电位滴定法。Salt content determination is a very important data in crude oil evaluation.The advantages and precautions of potentiometric titration in the determination of salt content were discussed.Compared with indicator titration,potentiometric titration is more accurate because the end point of titration is determined by the instrument.Potentiometric titration is more representative than the electrometric method.The potentiometric titration should be used as arbitration method or in line with international trade.
