▎ 摘  要

NOVELTY - Preparation method of amphiphilic graphene oxide heavy oil viscosity reducer involves reacting mixture containing graphene oxide, a hydrophobic modifier, a coupling agent and a template agent USE - Preparation method of amphiphilic graphene oxide heavy oil viscosity reducer used for viscosity reduction of heavy oil includes huff and puff, oil displacement, and viscosity reduction of heavy oil in a wellbore (Claimed). ADVANTAGE - Amphiphilic graphene oxide thick oil viscosity reducer is prepared by modifying graphene oxide with a hydrophobic modifier, so that one side is hydrophilic and the other side is lipophilic, and it has the advantages of an oil-soluble viscosity reducer and a water-soluble viscosity reducer, at the same time, they overcome their shortcomings and are more widely used. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) Amphiphilic graphene oxide viscous oil viscosity reducer prepared by the preparation method. (2) Viscosity reducer comprises amphiphilic graphene oxide heavy oil viscosity reducer and at least one in the amphiphilic graphene oxide heavy oil viscosity reducer that the preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the emulsification and viscosity reduction effect of crude oil after 6 revolutions per minute stirring after the viscosity reducer is mixed with crude oil of the application (the emulsification effect is obvious, and there is no obvious layering).
