摘　　要：三元复合驱采出水碱度测定采用多种不同指示剂进行对比测试研究。实验结果表明,水样pH<12时,采用酚酞-甲基红及溴甲酚绿-甲基红有良好的测试效果;pH>12时,采用溴甲酚绿-甲基红可获得可靠的结果。因此,推荐使用溴甲酚绿-甲基红指示剂作为三元复合驱采出水碱度测定的方法。Varied indicators were applied for the determination of alkalinity in ASP flooding produced water. The results showed that the indicator of phenolphthalein and methyl red had the best effect when the pH value of water was less than 12, bromocresol green and methyl red could obtain reliable results when the pH value of water was greater than 12. So the mixed indicator of bromocresol green and methyl red could be recommended as the indicator for the determination method of alkalinity in ASP flooding produced water.
