【摘要】：利用丙烯酰胺(AM)與2-丙烯酰胺基-2-甲基丙磺酸(AMPS)作為原料,進行水溶液聚合,采用低溫復(fù)合引發(fā)體系制備高溫交聯(lián)酸用稠化劑P(AM-co-AMPS),通過單因素分析法確定最佳反應(yīng)條件;并對其純化樣品進行紅外表征,室內(nèi)性能評價。結(jié)果表明,該稠化劑酸溶性好,基液黏度隨稠化劑加量增加而增大,配方:20%HCl+0.8%稠化劑+5%BZ酸化緩蝕劑+2%BZ措施用破乳助排劑+2%BZ酸化用鐵離子穩(wěn)定劑+0.3%BZ交聯(lián)延遲劑。加入交聯(lián)液(交聯(lián)劑/交聯(lián)延遲劑=1,交聯(lián)比∶100∶0.8),90 s后能形成可挑掛凍膠,180℃,170 s~(-1)剪切速率下,剪切100 min,黏度保持在56 mPa·s左右。加入破膠劑后,在90℃加熱1 h,破膠黏度為10 m Pa·s,利于酸液返排,可滿足高溫儲層對交聯(lián)酸的要求,具有較好的發(fā)展前景。
[Abstract]:Acrylamide amylase (AM) and 2-acrylamido-2-methylpropanesulfonic acid (AMPS) were used as raw materials to polymerize in aqueous solution. The high temperature crosslinking acid thickener Pu AM-co-AMPS was prepared by low temperature composite initiator system. The optimum reaction conditions were determined by single factor analysis. The purified samples were characterized by IR and evaluated in laboratory. The results show that the thickener has good acid solubility, and the viscosity of base liquid increases with the increase of thickener content. The ratio of 0: 20HCl 0.8% thickener 5BZ corrosion inhibitor 2BZ is used as demulsifier and draining aid 2BZ as iron ion stabilizer 0.3BZ crosslinking delay agent for acidizing. Adding crosslinking liquid (crosslinking agent / crosslinking delay agent 1, the crosslinking ratio is 100: 0.8 ~ 90 s) shear rate can be formed at 180 鈩，
