固体延缓交联剂研制与评价

Development and Evaluation of Solid Delaying Ligand

介绍了固体延缓交联剂研制方法。研究了水质、交联剂浓度、pH值对凝肢体系胶凝时间的影响。着重探讨了交联剂浓度、pH值对污水配制HPAM聚合物溶液在80℃、隔氧条件下、长期老化后粘度的影响情况。

This paper introduced a kind of making solid delaying ligand,and at the time,estimated the character of it. The effects to the gelation time of water, the temperature , the pH value, the concentration of crosslink have been studied. The paper especially discussed how pH value,the concentration of crosslink affect the viscosity of HPAM polymer solution at 80℃ antioxygen and long aged. When polymer flood takes enhanced oil recovery the study may give rise to great economy and society benefit.
