| 摘 要： | 采用美国Millipore切向流超滤系统，在消除了油井产出液中盐等杂质影响的前提下，准确测定了产出液中聚丙烯酰胺的相对分子质量和水解度，并与注入聚丙烯酰胺的相对分子质量和水解度进行了对比。结果表明，油井采出的聚丙烯酰胺的相对分子质量大幅度降低，而水解度明显提高；传统方法所测的油井采出液中的聚丙烯酰胺的质量浓度明显偏低。

| Abstract: | On the premise that the effects of salt and other impurity substances are eliminated, the relative molecular weight and degree of hydrolysis of polyacrylamide in produced fluid of polymer flooding reservior were accurately determined by ultra filtration technique, which were compared with that of injected polymer. The results show that the relative molecular weight of polyacrylamide decreases greatly, but the degree of hydrolysis of polyacrylamide incrcases obviously by this method, and the polyacrylamide concentration in produced fluid determined by traditional method is on the low side. |
