以丙烯酸( AA)、丙烯酰胺( AM),2-丙烯酰胺基-2-甲基丙磺酸( AMPS)、丙烯酰氧乙基三甲基氯化铵( DAC)作为单体合成了一种聚合物凝胶,单体以地下交联的方式进行调剖。通过正交-单因素实验法,以成胶时间和强度为指标,筛选出了合成的最佳条件,即单体浓度为10%(以反应物总质量为基准),单体配比为m(AA)/m(AM)=3∶7,交联剂加量为0．1%,引发剂加量为0．13%,功能单体加量AMPS为5%,DAC加入量为5%(以上均以单体总质量为基准)；用瓶测法判断成胶强度,60℃下成胶时间为4 h( B级,黏度5000 MPa·s),48 h能达到I级刚性凝胶。利用FTIR,1 HNMR 证实了聚合物凝胶的结构；聚合物凝胶60℃下老化35 d,平均脱水率为7．8%,随配制水矿化度的增大(8000~30000 mg/L)成胶时间由5 h降低到3 h,形成的凝胶强度变化不大；通过室内岩心流动实验对体系性能进行研究,该调剖剂具有较好的封堵性与耐冲刷性能。

A polymer gel were prepared by acrylic acid (AA), acryl amide (AM) ,2-Acryloylamino-2methyl-1-pro-panesulfonicacid (AMPS), (2-(acryloyloxy) ethyl) triemthylammonium chloride (DAC). Monomer for profile control in the form of underground cross linking. By orthogonal -single factor experiment, the synthesis filter out the best condi-tions, monomer concentration of 10%(On the basis of reactants total quality), a monomer ratio of m(AA)/m(AM) =3∶7, cross linking agent dosage 0. 1%, initiator dosage 0. 13%, AMPS dosage 5%, DAC dosage 5%( above have been monomer total quality as a benchmark). Bottle into a plastic measuring method to determine the strength, gel time at 60℃ for 4 hours (B grade, viscosity 5 000 MPa·s), after 48 hours the gel strength level I can reach. By means of FTIR and 1HNMR,the structure of the polymer gel is proved. Polymer gel at 60℃ aging 35 d, dehydration was 7. 8% on aver-age;with increasing water salinity (8 000~30 000 mg/L), a gel time of 5 h reduced to 3 h, gel strength changed little;in the core flow experiments, the profile control agent has good sealing and erosion resistance.
