【摘要】：研究了超聲波輔助強氧化劑對Cr~(3+)/HPAM凝膠體系解堵降粘的效果及機理。結果表明,超聲波處理后,凝膠的降粘率可達99.95%,與強氧化劑單獨降解相比,凝膠的交聯(lián)節(jié)點更為疏松,空間層狀密集結構受到了更嚴重的破壞,且Cr(Ⅲ)低聚物單體與聚丙烯酰胺單體顯著增多,聚集體明顯減少。模擬驅替實驗中,超聲波輔助強氧化劑解除凝膠堵塞作用明顯,滲透率恢復率達到38.9%,超聲波與強氧化劑間的協(xié)同作用對凝膠降解促進明顯,具有實用性意義。
[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，
