低浓度HPAM／A1Cit体系的评价及其成胶性能影响因素研究

THE STUDY AND THE EVALUATION ON LOW CONCENTRATION HPAM/AICiT AQUEOUS COL LOID DISPERSION GELS

摘要: 分别用粘度法和微孔滤膜法研究了部分水解聚丙烯酰胺／柠檬酸铝交联体系(CDG)的形成，并用微孔滤膜法研究了多元醇类物质、酚类物质、油田用缓蚀阻垢剂及油田回注水对CDG交联体系的影响。结果表明，粘度法不能用于评价低浓度的CDG体系交联情况，但可用微孔滤膜法评价；多元醇对CDG体系基本无影响；微量的酚类物质会严重影响交联聚合物的形成；舍磷酸基团的缓蚀阻垢剂对CDG的影响很大；改变交联比，可以用油田回注水配制CIDG体系，最佳交联比为10：l。

Abstract: The formation of the low concentration HPAM/AICit colloid dispersion gels (CDG) is investigated by the viscidity method and microporous filter method. The influences factors, such as manu - hydroxy alcohol, hydrox ybenzene, corrosion/scale inhibitors and
