摘　　要：研究了一种油田矿场应用中检测样品中阴离子聚丙烯酰胺浓度的方法——透析薄膜干燥法。系统考察了聚合物浓度、相对分子质量及水解度变化对该方法测定结果的影响。结果表明,该方法具有较高的准确性,克服了常规的淀粉-碘化镉浓度检测法不适用于高温油藏产出液中阴离子聚丙烯酰胺浓度检测的缺点。Dialysis film drying method was studied in this paper for the determination of hydrolyzed polyacrylamide concentration in the oil field application.The effects of concentration,relative molecular weight and hydrolysis degree on the determination results were investigated.Results show that under different concentration,relative molecular weight and hydrolysis degree,dialysis film drying method has higher accuarcy,overcoming the shortcoming that the conventional starch-cadmium iodide method unsuitable for the polyacrylamide concentration detection in high temperature reservoir.
