Heavy oil viscosity reducer and preparation method thereof

The present invention belongs to the technical field of organic chemical industry, and relates to a heavy oil viscosity reducer and a preparation method thereof, the viscosity reducer is prepared by ternary polymerizationof fluorocarbon alcohol ether (methyl) acrylate, maleic anhydride and styrene, the preparation method comprises the following stesp: synthesis of fluorocarbon alcohol ether; synthesis of fluorocarbon alcohol ether acrylate, synthesis of a ternary polymer, and preparation of the viscosity reducer. The advantages are as follows: the viscosity reducer can significantly reduce the viscosity of a variety of heavy oil especially cycloalkyl heavy oil, can prevent wax from forming a network structure, also can make asphaltene and colloid highly dispersed. The viscosity reducer can make the colloid stabile in property, the heavy oil may not be layered by placing for long time, and the viscosity reducer is remarkable in viscosity reduction effect, low in cost, and facilitates oil transport and applicat
