| titleOfInvention | Preparation method of delayed-coagulation acrylamide single body profile control agent |
| abstract | The invention relates to a preparation method of a delayed-coagulation acrylamide single body profile control agent, which relates to the technical field of the petrochemical industry. The delayed-coagulation acrylamide single body profile control agent is formed by mixing an acrylamide single body, initiator, amine crosslinking agent, stabilizer, assistant and fresh water. The preparation method is low in cost, shearing-resisting, simple in construction process, capable of delaying the coagulation, long in initial gelatinizing time, high in final set strength, good in selectivity, ingressive, firm to seal, abrasion-resisting, long in validity, capable of reducing the pollution on an oil layer, effective for coordinating the contradiction of the interlayer and the plane and capable of realizing the purpose of deep profile control. The acrylamide single body delayed-coagulation profile control agent is used for adjusting a water absorption profile of a water injection well in the water injection development process of an oil field and sealing a fluid channeling passage, a high-permeable layer and a water outlet layer of the oil well, and can effectively increase the water drive swept volume and increase the oil recovery. |
