The invention relates to the recovery of heavy oil reservoirs, and more particularly to a supported catalyst-assisted microwave method for exploiting a heavy oil reservoir. The method includes: (1) injecting a slug of a supported catalyst fluid into the heavy oil reservoir; (2) placing a microwave generator in the heavy oil reservoir to perform volumetric heating on an oil layer containing the supported catalyst fluid; and (3) turning off the microwave generator and injecting water into the heavy oil reservoir for subsequent displacement, where a water injection rate is 3 m/d or less.

Supported catalyst-assisted microwave method for exploiting heavy oil reservoir

Disclosed belongs to the technical field of heavy oil extraction, and specifically relates to a viscosity reduction system for microwave extraction of heavy oil and a preparation method thereof. The viscosity reduction system is a magnetic graphene oxide. The viscosity reduction system added to heavy oil has a significant viscosity reduction effect after microwave treatment. The viscosity reduction system exhibits lipophilicity and can be adsorbed on oil droplets, so that the thermal effect of microwaves assisted by the viscosity reduction system mainly acts on a reservoir, which reduces heat loss during heat transfer. At the same time, the viscosity reduction system is magnetic, which helps directional regulation and separation under the action of a magnetic field.
