聚丙烯酰胺浓度测定方法综述

Summary of Determination Methods of Polyacrylamide Concentration

自聚合物驱在海上油田获得工业化推广试验以来,聚驱规模不断扩大,油井产出液中聚合物浓度不断升高。主要从各类聚合物浓度测定方法的作用机理、测定条件、研究进展和应用现状出发,综述了淀粉—碘化镉比色法、浊度法、色谱法、超滤浓缩薄膜干燥法、化学发光定氮法、氨电极法、沉淀法、粘度法和有机碳含量法9种测定方法,指出各方法在应用于油井产出液中聚合物浓度测定时存在的问题。最后提出未来聚合物浓度测定方法的发展趋势。

Since polymer flooding has been industrialized in offshore oilfields, the scale of polymer flooding has been expanding and the concentration of polymer in the production fluid of oil wells has been increasing. Starting from the mechanism, conditions, research progress and application status of various polymer concentration determination methods, 9 determination methods, including starch-cadmium iodide colorimetry, turbidimetric method, chromatographic method, ultrafiltration concentration film drying method, chemiluminescence nitrogen determination method, ammonia electrode method, precipitation method, viscosity method and organic carbon content method were reviewed. The problems existing in the application of these methods in the determination of polymer concentration in oil well production fluids were pointed out. Finally, the development trend of polymer concentration determination methods in the future was put forward.
