| Abstract: | The reaction characteristics of flocculus formed in the reaction of cationic polymer to hydrolyzed polyacrylamide (HPAM) and the mass ratio of cationic polymer to HPAM in complete reaction were investigated experimentally. The flocculus has good ability to reduce the core permeability and the capability of washout resistance. The flocculus has good sand carrying-capability when its concentration is high enough. The mass ratio of cationic polymer to HPAM is 30 to 1 when the polymers reacted fully. The permeability of the core cuts down by 88 percent in the presence of flocculus. The field test showed that the cationic polymer could be used to plug the oil well containing high concentration of HPAM. A good effect of oil stimulation and water reduction has been obtained. |
