【摘要】：研究了超聲波輔助強(qiáng)氧化劑對(duì)Cr~(3+)/HPAM凝膠體系解堵降粘的效果及機(jī)理。結(jié)果表明,超聲波處理后,凝膠的降粘率可達(dá)99.95%,與強(qiáng)氧化劑單獨(dú)降解相比,凝膠的交聯(lián)節(jié)點(diǎn)更為疏松,空間層狀密集結(jié)構(gòu)受到了更嚴(yán)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(qū)替實(shí)驗(yàn)中,超聲波輔助強(qiáng)氧化劑解除凝膠堵塞作用明顯,滲透率恢復(fù)率達(dá)到38.9%,超聲波與強(qiáng)氧化劑間的協(xié)同作用對(duì)凝膠降解促進(jìn)明顯,具有實(shí)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，
