| 摘 要： | Aqueous gels formed by the crosslinkage of Cr(III) with partially hydrolyzed polyacrylamide (HPAM), have been commonly applied in the field of petroleum production1. Polymer and surfactants are used in enhancement of oil recovery2. Some studies3 indicate that a strong interaction is existent between polyeletrolytes and oppositely charged surfactants. So it is very important to study the effect of cationic surfactants on the gelation process of crosslinkage of Cr(III) with HPAM. To o…

| Abstract: | The effect of cationic surfactant cetyltrimethylammonium bromide (CTAB) on the gelation of partially hydrolyzed polyacrylamide (HPAM) by Cr (III) was investigated by using rheological measurements. The results indicated that the CTAB concentration has a pronounced effect on the viscoelastic properties of the gelling system. |
