| titleOfInvention | Polymer with selective water plugging function and preparation method and application thereof |
| abstract | The invention relates to the research field of profile control and water shutoff materials of oil fields and improvement of oil well productivity of oil reservoirs in high water cut periods, and discloses a polymer with a selective water shutoff function, wherein the polymer is prepared by carrying out polymerization reaction on emulsion containing a monomer A, a monomer B, a monomer C and an emulsifier in the presence of an initiator and water serving as a solvent, wherein the monomer A is acrylamide; the monomer B is fumaric acid; the monomer C is an oil-soluble monomer, and the oil-soluble monomer is styrene and/or octyl methacrylate; the emulsifier comprises a primary emulsifier and/or a co-emulsifier. The polymer prepared by the invention has excellent effects of selectively blocking water but not oil, and has higher scouring resistance times. |
