摘　　要：以聚丙烯酰胺(分子量300万,水解度<3.0%)为主剂,六羟甲基三聚氰胺(HMM)为交联剂,制得PAM/HMM调堵剂。结果表明,制备六羟甲基三聚氰胺的条件为:三聚氰胺为23.6 g,甲醛溶液(37.0%)为152.2 g,蒸馏水为24.2 g,pH值为9.0,反应温度为60℃,反应时间为4 h;当PAM为7.10 g,HMM为3.16 g,蒸馏水为100mL,pH值为5.0,反应温度为100℃,反应时间为4 h,制得PAM/HMM调堵剂黏度最高,为1 754 000 mPa.s;在粗盐浓度为10.0～300.0 g/L,CaCl2浓度为10.0～250.0 g/L时均能成胶且凝胶稳定性很高,可应用于高温高盐油藏的堵水调剖。Using PAM（ molecular weight 3 000 000, hydrolysis degree 〈 3.0% ） as main agent, hexmeth- ylol melamine（HMM） as the erosslinking agent to formulate various PAM/HMM plugging agent. The re- suits showed that preparation of HMM conditions were as follows ： the melamine content is 23.6 g, the formaldehyde solution （37 % ） content is 152.2 g, the distilled water is 24.2 g, the pH is 9.0, the reaction temperature is 60℃, the reaction time is 4 h. When the PAM content is 7.10 g,the HMM content is 3.16 g,the volume of the distillation water is 100 mL, the pH value is 5.0, the reaction temperature is 100 ℃ ,the reaction time is 4 h, PAM/HMM plugging agent can be prepared, and the viscosity value is maximum, 1 754 000 mPa ·s ; in the salt concentration of 10.0 - 300.0 g/L, and CaC12 concentration of 10.0- 250.0 g/L, it can appears gelation and the gets have high stability, which can be used in water shutoff and profile control in high temperature and high salinity reservoirs.
