【Abstract】 A compound type of vicious reductant for highly vicious crude oil, which was composed of acrylamide, maleic anhydride, styrene and octadecanol, was prepared ,The influence of the ratio of reaction mass to viscous reductant and the quantity of viscous reductant on reducing viscosity effect was studied . Under the operational conditions of temperature 50 ℃ and the shearing rate 100 s\+\{-1\},highly viscous crude oil which has viscosity of 5 500 mPa·s was measured .The result showed that the viscosity decreased by 57.5 percent when the quantity of 0.5 percent vicious reductant was added to the highly viscous crude oil. This viscous reductant prepared had a good effect of decreasing viscosity.更多还原
