研制以聚丙烯酰胺（HPAM ）为主剂、酚醛复合物和有机金属络合物为交联剂的耐温抗盐型复合交联弱凝胶体系，并与单一交联弱凝胶体系进行性能比较。结果表明，耐温抗盐型复合交联弱凝胶体系的优选配方为：HPAM、氯化铵、酚醛复合交联剂、有机金属络合物交联剂的质量浓度分别为1000、3000、300、25 mg／L ；与单一交联弱凝胶体系相比，复合交联弱凝胶体系在相同矿化度盐水中成胶，其黏度是单一交联弱凝胶体系黏度的8～10倍，在相同的温度下其黏度是单一交联弱凝胶体系黏度的3～4倍，在75℃下老化120 d ，其黏度依旧能保持在初始黏度的80％以上，具有优良的耐温、抗盐性能和良好的长期稳定性。

With HPAM as the main agent and phenolic compounds and organometallic complex as crosslinking agents ,heat-tolerant and salt-resistant compound crosslinking weak gel system was de-veloped .The results show that the best formula for the preparation of compound crosslinking weak gel system is HPAM at 1000 mg/L ,chloride at 3000 mg/L ,phenolic compound at 300 mg/L ,and an organic metal compound crosslinking agent at 25 mg/L .Compared with the single crosslinking weak gel system ,the compound crosslinking system boasts a viscosity 8 to 10 times that of the former un-der the same condition of salinity . Under the same temperature , the viscosity of the compound crosslinking system is 3 to 4 times that of the single crosslinking system .Placed at 75 ℃ for 120 days ,the compound crosslinking system’s viscosity is still 80% of its initial viscosity ,w hich indicates that the compound crosslinking system has excellent heat tolerance ,salt resistance and good long-term stability .
