生物高分子HCP与聚丙烯酰胺HPAM的交联性能与应用

Charaterization and Performance of the Cross-linked Systems HCP and HPAM

研制了一种生物高分子交联剂HCP,并使其与部分水解聚丙烯酰胺HPAM的水溶液进行交联.通过光度分析、室内岩心实验及测试电导率和粘度等方法评价了交联聚合物的性能.实验结果表明,交联剂HCP与HPAM之间的确可以产生交联作用,而且交联得到的凝胶具有良好的增粘、耐温性能;交联产物可以用于窜聚井的封窜和注聚井剖面调整.

The quaternary ammonium of polysaccharide （HCP） is synthesized and used a cross-linking reagent in the aqueous systems of partly hydrolyzed polyacrylamide （HPAM）.The ultraviolet spectroscope, viscosity, conductivity and stability at higher temperature of the cross-linked systems are characterized. The study clearly indicates that the cross-linked systems has a better viscosity pmrovity and durability under the condition of high temperature. The cross-linked flocculate can be used for the aim of plugging polymer channeling and of controlling reservoir permeability.
