VISCOSITY REDUCTION SYSTEM FOR MICROWAVE EXPLOITATION OF HEAVY OIL AND PREPARATION METHOD THEREOF

Title:

VISCOSITY REDUCTION SYSTEM FOR MICROWAVE EXPLOITATION OF HEAVY OIL AND PREPARATION METHOD THEREOF

Document Type and Number:

WIPO Patent Application WO/2020/206869

Kind Code:

A1

Abstract:

The application relates to a viscosity reduction system for microwave exploitation of heavy oil and a preparation method thereof. The viscosity reduction system is magnetic graphene oxide. Adding the viscosity reduction system to heavy oil provides a significant viscosity-reducing effect after microwave treatment. The viscosity reduction system exhibits lipophilicity and can be adsorbed on oil droplets. Accordingly, the microwave-augmenting thermal effect thereof mainly acts on the oil layer, and as a result heat loss in the heat transfer process is decreased. The viscosity reduction system is magnetic, facilitating directional control and separation under the action of a magnetic field.
