| 摘 要： | 大庆油田聚合物驱和三元复合驱中普遍采用冰醋酸－次氯酸钠浊度法测定ＨＰＡＭ浓度，由于应用条件复杂多变，测定结果的准确性不好。实验考察了ＨＰＡＭ的水解度，分子量，水质碱、表面活性剂ＯＲＳ－４１及ＨＰＡＭ生产厂家对测定结果的影响 发现除ＯＲＳ－４１外，其余因素的影响都很大，这使实际生产中很难制作出合乎该法要求的标准工作曲线。 |

| Abstract: | The turbidimetric glacial acetic acid/sodium hypochlorite method for determining HPAM concentration in aqueous solutions involved in EOR operations often give unexplainable results. In this paper the influences on HPAM concentration determinations of HD and M of HPAM, water quality, NaOH, surfactant ORS 41, and sources of HPAM are investigated and shown to be notable (besides of ORS 41). These influences with the unsuitable standard working graphs constructed lead to uncaccurate determinations. This method must be improved. |
