摘要：利用丙烯酰胺（AM）、3-(N,N-二甲氨基丙基)甲基丙烯酰胺（DMAPMA）、十八烷基二甲基烯丙基氯化铵
（DMAAC-18）和 4-丙烯酰吗啉（ACMO），通过自由基水溶液聚合得到了一种初始黏度低，并随着酸岩反应自
动增稠的酸化自转向剂 ADDA。通过单因素实验得到 ADDA 的最佳合成条件为：单体配比 n(AM)∶
n(DMAPMA)∶n(DMAAC-18)∶n(ACMO) = 90∶10∶1.8∶10，引发剂含量（以单体总质量为基准，下同）为 0.5%，

单体含量（以单体溶液总质量为基准，下同）为 30%，反应温度 55 ℃，反应时间 6 h，pH=7。利用 FTIR 和 HNMR
对产物结构进行确证。在 90 ℃下，1.3%（以 HCl 溶液总质量为基准，下同）ADDA 酸液黏度能从 ADDA 鲜酸

Abstract: An acidizing self-diverting agent ADDA with low viscosity and automatic thickening with acid
rock reaction was obtained by free radical aqueous solution polymerization of acrylamide (AM), 3-(N,N-
dimethylaminopropyl)methylacrylamide (DMAPMA), octadecyldimethylallylammonium chloride (DMAAC-
18) and 4-acryloylmorpholine (ACMO). The optimal conditions for the synthesis of ADDA were obtained
by single factor of experiment as follow: n(AM)∶n(DMAPMA)∶n(DMAAC-18)∶n(ACMO) = 90∶
10∶1.8∶10, initiator dosage (based on the total mass of monomers, the same below) of 0.5%, monomer
content (based on the total mass of monomer solution, the same below) of 30%, reaction temperature of
55 ℃, reaction time of 6 h and system pH of 7. The structure of product was characterized by FTIR and
1 HNMR. At 90 ℃, the apparent viscosity of 1.3% (based on the total mass of HCl solution, the same below)
ADDA acid viscosity increased from 6 mPa·s of ADDA fresh acid to 126 mPa·s, which had good diverting
performance. The apparent viscosity of 1.3% ADDA spent acid was 70 mPa·s after shearing at 90 ℃ for
–1
1 h at 170 s , indicating that ADDA spent acid had good temperature resistance. At 90 ℃, the apparent
viscosity of 1.3% ADDA self-diverting acid of spent acid with iron ion stabilizer, drainage aid and high
temperature corrosion inhibitor was increased by 54 mPa·s compared with that 1.3% ADDA without
acidification admixture, indicating that ADDA processed good compatibility.
