Abstract:

By analyzing the mechanism of oil-soluble viscosity reducer, we investigated the viscosity reduction effect of monomer (octadecyl acrylate, styrene, maleic anhydride), and synthesized a variety of oil-soluble copolymer as viscosity reducers. The results show that the product is better by the controlling the monomer ratio. When the monomer ratio was 6∶2∶1 and the concentration of viscosity reducer was 0.01%, the viscosity reduction rate is 40% or more, and stability of viscosity reduction effect is well.
