【摘要】：為滿足不壓井作業(yè)對凍膠新材料的性能要求,對羧甲基纖維素凝膠合成進行了系統(tǒng)性的分析研究,制備出一種高強度、抗剪切、能夠?qū)崿F(xiàn)自破膠且破膠時間可控的改性羧甲基纖維素(CMC)智能膠體。該膠體的最優(yōu)質(zhì)量分數(shù)分別為:水79.41%,CMC 1%,丙烯酰胺8%,NaCl 0.5%,固化劑0.45%,過硫酸銨0.02%,有機交聯(lián)劑0.02%,自制破膠劑10%,增黏劑0.6%。膠體最大本體強度可達44.5 N,最佳成膠溫度范圍為70~80℃,加入自制膠囊破膠劑后可實現(xiàn)38~70 h膠體的可控破膠,破膠殘液為深棕黃色液體,利于返排。
[Abstract]:In order to meet the performance requirements of the new gel material, the synthesis of carboxymethyl cellulose gel was studied systematically and a kind of high strength and shear resistance was prepared. The intelligent colloid of modified carboxymethyl cellulose (CMC) can be realized with self-breaking and controlled breaking time. The optimum mass fractions of the colloid were: water 79.41 and CMC 1, acrylamide 8 and NaCl 0.5, curing agent 0.45, ammonium persulfate 0.02, organic crosslinking agent 0.02, self-made gel breaking agent 10 and thickener 0.6. The maximum bulk strength of the colloid can reach 44.5 N, and the optimum gelation temperature range is 7080 鈩，
