| 摘 要： | 由于海上油气田目前应用行业标准在现场水质检测时存在缺陷，特别是CO3^2-和HCO3-等离子的特殊易变性，因此开发出一套适合于现场的快速、准确全新水质分析方法具有重要意义。上海采油技术服务公司首次利用CO2等离子选择性电极对海上油田水中易变离子用仪器直接测定，得到了现场验证。该离子进行测定并与传统的酸碱滴定方法进行对比发现，CO2电极法测定与酸碱滴定法测定结果基本一致，且方法更简便，更适合现场测定。

| Abstract: | It is important to measure the concentration of the CO3^2- and HCO3- ions locally and quickly clue to their special changeability and the＇ disadvantages of the present analytical standard. CO2 and other ion selective electrodes was used to determine the changeable ions in water of offshore oilfield for the first time. Compared with traditional acid-base titration, the results of selective electrodes are almost the same. Additionally, it is more convenient and suitable for the local determination of the CO3^2- and HCO3 - ions by using the CO2 electrode. |
