摘　　要：为了进一步将冻胶封堵技术应用在管道快速封堵作业中,对丙烯酰胺-丙烯酸冻胶与长输管道间黏附力特性进行研究,设计了一种丙烯酰胺/丙烯酸体系冻胶与钢制基底黏附力的测力方法,构建了该方法下测量黏附力的评价体系;通过正交试验研究了冻胶配方中单体配比、引发剂质量分数、交联剂质量分数、中和度对冻胶与金属管道黏附力特性的影响规律,分析讨论了各因素对黏附力特性的影响机理;借助MATLAB软件构建了丙烯酰胺-丙烯酸冻胶体系与管道之间黏附力的数学模型,并对模型的正确性进行了检验。实验结果表明,当工艺参数为单体配比1∶ 1,引发剂质量分数0.3%,交联剂质量分数0.25%,中和度65%时黏附力达到最大。其中单体配比对黏附力的影响最为显著,黏附力随着单体配比的增大而减小,随着引发剂质量分数的增加而增大,随着交联剂质量分数的增加而增大,随着中和度的增加而先增大后减小。数学模型的检验结果表明该模型具有普适性。冻胶与管道黏附力特性研究结果为冻胶封堵技术的开展做了基础工作。In order to apply gel plugging technology to the fast plugging operation of pipeline,the characteristics of adhesion force between acrylamide-acrylic gel and long-distance pipeline were studied.A new measuring method and evaluation index system of the adhesion force between gel and metal were established.The influences of monomer ratio,initiator concentration,crosslinker concentration and neutralization degree on the characteristics of adhesion force between acrylamide-acrylic gel and metal pipeline were studied by orthogonal test,and the influence mechanisms of the factors were analyzed.The mathematical model of the adhesion force between acrylamide-acrylic gel and pipeline was established by means of MATLAB software and the correctness of the model was verified.The experimental results show that the adhesion force reaches maximum when the mass ratio of the monomersis 1∶ 1,the mass fraction of initiator and crosslinker is 0.3% and 0.25% respectively,and the neutralization degree is 65%.The monomer ratio has the most significant influence on the adhesion force.The adhesion force decreases with the increase of the monomer ratio,increases with the increase of the mass fraction of initiator and crosslinker,and increases first and then decreases with the increase of the neutralization degree.The verification result of the mathematical model shows that it is universal.
