| titleOfInvention | Thick oil viscosity reducer and preparation method and application thereof |
| abstract | The invention discloses a thick oil viscosity reducer and a preparation method and application thereof. The thickened oil viscosity reducer is a quaternary oligomer AM-SA-PB-AMPSNa and is formed by polymerizing four monomers, namely Acrylamide (AM), Acrylic Acid (AA), 4-phenyl-1-butylene (PB) and acrylamide-2-methylpropanesulfonic Acid (AMPS). The thick oil viscosity reducer has the advantages of good viscosity reducing effect, low cost, no rebound viscosity after standing and the like, and is simple in preparation process, low in cost and suitable for practical application in oil fields. |
