【摘要】 该文研究了不同水质配制时聚合物溶液的粘度及老化一定时间后的粘度保留率 ,以HPAM降解与稳定的机理为指导 ,筛选出了两种粘度稳定性较好的驱油体系 ,它们在 75℃、隔氧条件下长时间老化后 ,粘度有增加的趋势 ,这对污水配制聚合物溶液进行三次采油有一定的参考价值更多还原

【Abstract】 Viscosity losses in polymer solution made up by various water qualities have been studied. Two oil displacement systems with good stability in viscosity have been screened with the guide of the mechanism of HPAM polymer degradation and stability. After aging for a long time on the condition of oxygen exclusion and at 75℃, the viscosity of the two systems has the trend of increase. This result is of reference value to tertiary recovery through polymer made up by sewage.更多还原
