摘要

驱油用聚丙烯酰胺的分子量分布是评价聚合物的重要指标之一，对聚合物驱油效果有重要的影响。目前测定驱油用聚丙烯酰胺分子量分布的主要方法有光散射法、凝胶渗透色谱法、凝胶渗透色谱法联用技术和流变法等。对这几种常用的分析方法做了详细介绍，对比分析了它们的特点和适用范围，对这些方法和技术做了展望。光散射法多为研究所用。凝胶渗透色谱法比较简单且实验精确度比较高。凝胶渗透色谱联用技术不仅拓宽了测定范围而且提高了灵敏度，但是应用凝胶渗透色谱测量聚合物分子量分布仍有大量研究工作。流变法省却了溶解聚合物的步骤，解决了高分子量及长链支化度聚合物的测试灵敏度不高的问题，具有比较广阔的发展前景。

Abstract

Molecular weight distribution of polyacrylamide(PAM) which is used for flooding is one of the most important indexes for evaluating polymer. Polymer flooding has been important influence on molecular weight distribution of polymer which is used for flooding. At present

the methods on determination of molecular weight distribution have mainly light scattering method

Gel Permeation Chromatography (GPC)

GPC coupling technique and rheology method etc. It is introduced these analysis methods and its application range in detail introduction

compared their features and scope and looked the development trend of method and technique. Light scattering method is mainly used for research. GPC method has advantages of simple and high experiment accuracy. GPC coupling technique not only can widen the range of application but also improve the sensitivity. However

the application of molecular weight distribution measurement of GPC still needs to make amount of research. Rheology method has well development because it can save the stage of dissolving polymer; meanwhile

it can resolve the problem of low sensitive which is the polymer owed high molecular weight and long-chain degree of branching.
