【摘要】：研究了超声波辅助强氧化剂对Cr~(3+)/HPAM凝胶体系解堵降粘的效果及机理。结果表明,超声波处理后,凝胶的降粘率可达99.95%,与强氧化剂单独降解相比,凝胶的交联节点更为疏松,空间层状密集结构受到了更严重的破坏,且Cr(Ⅲ)低聚物单体与聚丙烯酰胺单体显著增多,聚集体明显减少。模拟驱替实验中,超声波辅助强氧化剂解除凝胶堵塞作用明显,渗透率恢复率达到38.9%,超声波与强氧化剂间的协同作用对凝胶降解促进明显,具有实用性意义。
[Abstract]:The effect and mechanism of ultrasonic assisted strong oxidant on plugging and viscosity reduction of Cr~ (3) / HPAM gel system were studied. The results show that the viscosity reduction rate of the gel can reach 99.95% after ultrasonic treatment. Compared with the degradation of strong oxidant alone, the crosslinking node of the gel is looser and the dense structure of space layer is destroyed more seriously. Cr (鈪，
