▎ 摘  要

NOVELTY - Thick oil viscosity reducer composition comprises low molecular weight amphiphilic polymers and nano-hydrophobic modified materials. The mass ratio of the low-molecular-weight amphiphilic polymer and the nano-hydrophobic modified material is 100:0.1-2. The average molecular weight of the low molecular weight amphiphilic polymer is between 100000-500000. USE - The thick oil viscosity reducer composition is useful for viscosity reduction of heavy oil transported by pipelines, and viscosity reduction of heavy oil in cold recovery, and used as an auxiliary viscosity reducer for heavy oil wellbore viscosity reduction, and oil field chemical agents. ADVANTAGE - The method: adopts polymerization reaction to obtain reaction product. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing thick oil viscosity reducer composition comprising uniformly mixing the low molecular weight amphiphilic polymer and nano hydrophobic modified material to obtain the thick oil viscosity reducing agent composition.
