摘　　要：由于油田采出水中Na^+、Ca^(2+)、Mg^(2+)、Fe^(2+)等离子及悬浮物、细菌的存在,使采用油田回注污水配制的HPAM(部分水解聚丙烯酰胺)-酚醛树脂交联可动凝胶性能变差,并且随污水中离子浓度增加,对凝胶性能影响越严重。为提高回注污水配制可动凝胶的性能,试验研究了降低Ca2+、Mg^(2+)、Fe^(2+)等离子对凝胶性能影响的添加剂NHCS配方。通过试验,在油田回注污水中加入与Ca^(2+)、Mg^(2+)、Fe^(2+)离子等量反应的添加剂NHCS,同时通过对污水进行搅拌等措施,使污水配制可动凝胶的黏度达到同浓度清水配制的70%以上,有效提高了油田回注污水配制可动凝胶的交联黏度和稳定性能。This paper describes the existence of Na^+,Ca^(2+),Mg^(2+),Fe^(2+)suspended materials,bacteria,etc.in the produced water from oilfields,which induces a deterioration of HPAM-phenol formaldehyde resin gel.Besides,the influence of the above ions is much more serious with the increase of the ions concentrations.Therefore,the additive formulation is studied in order to reduce the impact of Ca^(2+),Mg^(2+),Fe^(2+)and improve the gel performance.The experiment indicates that adding NHCS to the sewage while stirring could make the movable gel viscosity more than 70% of the gel prepared with clear water.This method can effectively improve the viscosity and stability of the movable gel prepared with backfilling waste water.
