| titleOfInvention | Polyacrylamide reverse microemulsion and preparation method thereof |
| abstract | The present invention relates to a kind of polyacrylamide reverse microemulsion and preparation method thereof, the problem that mainly present in solution prior art, product solid content is low and emulsion is unstable.Aqueous phase containing monomers such as acrylamides, by the method using semi-continuous polymerization, is dividedly in some parts in the oil phase containing emulsifying agent by the present invention so that the polymerization process of microemulsion controls more steadily and microemulsion good stability, can to separate out solid content higher.In terms of weight of microemulsion number, comprise the oil-dissolving solvent of 20 ~ 70 parts, 5 ~ 20 parts of emulsifying agents and co-emulsifier, the technical scheme containing acrylamide polymer aqueous phase of 20 ~ 70 parts, preferably resolving this problem, prepared polyacrylamide reverse microemulsion directly or improves the on-the-spot application of recovery ratio with other oil field chemicals for tertiary oil production in oil field depth profile control, water blockoff, the displacement of reservoir oil etc. after compounding. |
